Lord, Teach us to Pray

8. Forgive us our Sins

 

Introduction: The heartbeat of the Gospel

If “Give us today our daily bread” addresses our physical need, then “Forgive us our sins” addresses our deepest spiritual need. It brings us to the heart of the gospel – the truth that we are sinners in need of mercy, and that God, through Jesus Christ, freely forgives. This petition is more than a request. It’s a confession, a cry for grace, and an invitation into the rhythm of mercy. Here, Jesus teaches us not only to seek forgiveness but to live as people shaped by it – offering the same grace to others that we ourselves have received.

The necessity of forgiveness

Before we can pray this line sincerely, we must come to terms with a simple but often resisted truth: we need forgiveness. Romans 3:23 states: “For all have sinned and fall short of the glory of God.” Sin is not just breaking rules – it’s rebellion against the heart and will of God. It’s choosing our way over His, whether through pride, deceit, lust, greed, or neglect. It infects both our actions and our intentions. We often like to think of ourselves as “good people who sometimes make mistakes.” But Scripture tells us that sin is deeper than error – it is a condition. And the only remedy is the mercy of God. To ask God to forgive us is to humbly admit that we have fallen short – and that we cannot fix ourselves. This is a deeply countercultural truth in a world that prizes self-sufficiency and moral relativism.

God’s desire to forgive

But just as we must see the truth of our sin, we must also see the greater truth of God’s mercy. Psalm 86:5 says: “You, Lord, are forgiving and good, abounding in love to all who call to you.” This is Who God is – not a reluctant judge but a compassionate Father, eager to pardon. Throughout Scripture, God reveals Himself as the One Who forgives sin, cleanses guilt and removes our transgressions “as far as the east is from the west.”(Psalm 103:12). Forgiveness is not something God offers begrudgingly – it flows from His very character. This is why Jesus could tell stories like the parable of the prodigal son (Luke 15), where the father runs to embrace the returning rebel. That’s the kind of God we pray to when we say, “Forgive us our sins.”

Forgiveness through Christ

Of course, God’s forgiveness is not arbitrary – it is costly. It flows to us through the blood of Jesus Christ. Paul tells us: “In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God’s grace.” (Ephesians 1:7). The cross is the foundation of our forgiveness. Jesus bore the weight of our sin. He paid the debt we could never repay. When we ask for forgiveness, we are not hoping that God might overlook our sin – we are standing on the finished work of Christ, who has already dealt with it. This is why forgiveness is both free and serious. Free – because it’s a gift of grace. Serious – because it cost Jesus everything.

Confession and repentance

This petition also teaches us that our experience of forgiveness and confession are linked. We must name our sins before God – not to inform Him (He already knows), but to align our hearts with truth. 1 John 1:9 assures us: “If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.” Confession is not about wallowing in shame – it’s about stepping into the light. It’s the doorway to healing and restoration. True confession also moves us into repentance – a turning away from sin and toward God. When we say, “Forgive us our sins,” we are not merely asking for a clean slate. We already have that, in Christ. We are expressing our desire to be changed – to walk in newness of life. We are asking that the power of forgiveness would change our attitudes and actions.

Daily forgiveness for daily sin

It’s important to note that Jesus places this petition in a daily prayer. Just as we ask for daily bread, we ask for daily grace. This doesn’t mean we are constantly being re-saved – but it does mean we need continual renewal in our relationship with God. Even as believers, we stumble. We fail. We forget who we are. We forget that we are already forgiven and we can easily take that for granted. And so we return – daily – to the fountain of mercy. Not to earn God’s love and grace, but to experience it afresh.

Jesus illustrated this beautifully when He washed His disciples’ feet in John 13. Peter, at first, resisted. But Jesus said: “Unless I wash you, you have no part with me.” (John 13:8). And then He clarified: “Those who have had a bath need only to wash their feet; their whole body is clean.” (John 13:10). In other words: you’ve been made clean, but you still need your feet washed. We come to God daily with dusty feet, and He kneels, tenderly, to cleanse us again.

When we pray, “Forgive us our sins,” we are not grovelling before a hard-hearted deity who hasn’t forgiven us. We are returning to the One Who ran to meet the prodigal. We are opening ourselves to the grace that flows from the cross. We are being restored – not just to innocence, but to intimacy with God. This is the gospel in prayer form: we are sinners, and God is merciful. We are broken, and He is the Healer. We fall short, and He lifts us up.

Forgiven people forgive people

The second half of this petition – “as we forgive those who sin against us” – is one of the most sobering and challenging lines in the entire Lord’s Prayer. It ties God’s forgiveness of us to our forgiveness of others. Jesus connects the mercy we receive from God to the mercy we give to others. At first glance, this may seem transactional – as though God will only forgive us if we forgive others. But Jesus is not introducing a condition that earns forgiveness. That would completely undo the whole reality of salvation by grace, through faith.

Rather, He is describing the natural outworking of a heart that has truly experienced grace. He is talking about the impact and effect of forgiveness and unforgiveness. Those who know the weight of their own sin, and the wonder of their pardon, cannot help but extend forgiveness to others. It’s not always easy. But it’s always possible through the power of God’s Spirit.

Remarkably, this is the only line in The Lord’s Prayer that Jesus returns to and immediately expands upon after the prayer ends. In Matthew 6:14-15, He says: “For if you forgive other people when they sin against you, your heavenly Father will also forgive you. But if you do not forgive others their sins, your Father will not forgive your sins.”

Why does Jesus highlight this point so strongly? Because He knows how easily unforgiveness can poison the soul. Nothing blocks the effect and experience of grace in our lives like bitterness and forgiveness.

When we withhold forgiveness, we cut across the impact of the grace which God has lavished upon us in Christ. We don’t stop His grace, for it has already been given, once and for all, but we certainly stop its impactin our lives when we refuse to forgive. We may think we are punishing the offender – but we are the ones who become imprisoned. Jesus is clear: forgiveness is not optional for those who follow Him.

What forgiveness is – and what it is not

To obey this command, we need a clear understanding of what forgiveness actually means.

Forgiveness is:

  • Releasing someone from the debt they owe you.
  • Choosing to entrust justice to God.
  • Letting go of resentment and the right to revenge.
  • A decision – often repeated over time – to walk in grace.

Forgiveness is not:

  • Excusing or minimizing the offence.
  • Pretending the hurt didn’t happen.
  • Automatically restoring trust or relationship.
  • A denial of justice – rather, it entrusts justice to God.

Romans 12:19 reminds us: “Do not take revenge, my dear friends, but leave room for God’s wrath, for it is written: ‘It is mine to avenge; I will repay,’ says the Lord.” Forgiveness doesn’t mean injustice goes unanswered – it means we stop being judge and executioner and place the matter in God’s hands.

The parable of the unforgiving servant

To illustrate this truth, Jesus told a powerful parable in Matthew 18:21-35. Peter had asked, “Lord, how many times shall I forgive my brother or sister who sins against me? Up to seven times? ”Jesus replied, “Not seven times, but seventy-seven times.” Then He told the story of a servant who owed the king an unpayable debt – ten thousand bags of gold. When he begged for mercy, the king forgave the entire debt. But that same servant went out and found a fellow servant who owed him a small amount – a hundred silver coins – and had him thrown into prison when he couldn’t repay. When the king found out, he was furious: “‘You wicked servant,’ he said, ‘I cancelled all that debt of yours because you begged me to. Shouldn’t you have had mercy on your fellow servant just as I had on you?’”             (vv. 32-33). The message here is unmistakable: having been forgiven an infinite debt, we must extend forgiveness to others.

Forgiveness as a lifestyle

Forgiveness is not a one-time act – it is a lifestyle. People will hurt us, offend us, and disappoint us again and again. And Jesus calls us to keep forgiving. Colossians 3:13 says: “Bear with each other and forgive one another if any of you has a grievance against someone. Forgive as the Lord forgave you.”

This means that forgiveness becomes a reflex – a disposition of the heart, and not merely a reaction to extreme circumstances. It means cultivating a posture of grace in all our relationships, big and small.Forgiveness is one of the most powerful ways we bear witness to the gospel. When we forgive, we show the world what grace looks like. We reflect the heart of our Saviour.

What if I don’t feel like forgiving?

Forgiveness is not just a feeling – it is a decision. And often, it is a decision we must make before our emotions catch up. Jesus didn’t say, “When you feel ready, forgive.” He simply said, “Forgive.” Period.

This does not mean we deny our pain. It means we choose to surrender it to God. We say, “Lord, I don’t feel like forgiving – but I choose to release this person to You. Help me walk in this decision.” As we continue to pray that prayer, God softens our hearts. He replaces bitterness with peace. He does in us what we cannot do on our own. Forgiveness may be a process – especially in cases of deep trauma or betrayal. But it begins with a decision. And God is faithful to honour and empower that choice.

When we pray, “Forgive us our sins, as we forgive those who sin against us,” we are stepping into the flow of God’s grace. We are receiving mercy and passing it on. We are joining the rhythm of the kingdom, where forgiveness is both gift and calling. To forgive is not to pretend – it is to proclaim. It is to declare, by faith, that Christ’s grace is stronger than the wound, deeper than the pain, and greater than the debt. And as we walk this path, we become more like Jesus – who from the cross cried out, “Father, forgive them.”

Forgiveness and reconciliation

Forgiveness and reconciliation are deeply related, but not identical. Forgiveness is something we can offer unilaterally – we can forgive someone who never apologizes, who never admits their wrong, or who may no longer even be in our lives. Reconciliation, however, requires both parties. It depends on mutual honesty, repentance, and a willingness to rebuild trust.

Romans 12:18 encourages us: “If it is possible, as far as it depends on you, live at peace with everyone.”

Sometimes reconciliation is possible and beautiful – relationships are healed, families are restored, churches are renewed. But sometimes, for reasons totally beyond our control, full reconciliation is not achievable. Even so, forgiveness must still be given freely, or bitterness will fester. Forgiveness will open the door to reconciliation. It creates the possibility for peace. But even when reconciliation doesn’t happen, forgiveness still sets us free.

Forgiveness and freedom

Unforgiveness is a prison. It ties us to the past, chains us to the person who hurt us, and poisons our present with resentment. But true forgiveness breaks those chains. When we forgive, we’re not excusing the harm. We are choosing to live in freedom rather than remain enslaved to the offence. We are refusing to let bitterness take root.

Hebrews 12:15 warns: “See to it that no one falls short of the grace of God and that no bitter root grows up to cause trouble and defile many.” Bitterness doesn’t stay contained. It grows, spreads, and infects other areas of our life. But forgiveness cuts it off at the root. It reclaims our hearts for peace, not vengeance. We may think we are protecting ourselves by holding onto the pain. But the truth is, we’re healing ourselves by letting it go.

The practice of forgiveness in daily life

Forgiveness isn’t just for life’s major betrayals – it’s also needed in the small, daily interactions that may irritate, wound, or just disappoint us. A careless word. A forgotten promise. A repeated annoyance. In marriage, family life, church community – they all require frequent, deliberate forgiveness.

Colossians 3:13 says: “Bear with each other and forgive one another if any of you has a grievance against someone. Forgive as the Lord forgave you.” This isn’t an occasional act – it’s a lifestyle. When we live with this mindset, we become less reactive and more gracious. We don’t keep score. We don’t hold grudges. We become quick to say, “I forgive you.” And quicker still to say, “I’m sorry.” The Lord’s Prayer invites us to build forgiveness into the rhythm of our daily relationship with God – because we need it its power daily, and we need to offer it daily.

When forgiveness feels impossible

Some of us carry wounds so deep that the idea of forgiving feels impossible. The betrayal, the abuse, the injustice – it was real. It hurt. It may still hurt. Forgiveness doesn’t mean pretending the pain is gone. It doesn’t mean restoring a toxic relationship or ignoring wise boundaries. It means placing the wound in the hands of a God Who sees, Who knows, and Who heals.

Isaiah 61:1 speaks of the mission of Jesus: “He has sent me to bind up the broken-hearted… to proclaim freedom for the captives and release from darkness for the prisoners.” Only Jesus can do that. And only His Spirit can empower us to forgive what we cannot forgive on our own. If that’s where you are, start with this prayer: “Lord, I’m willing to be made willing.” That’s all it takes to begin. He will do the rest.

Forgiveness and the cross

All of this – the forgiveness we receive and the forgiveness we give – finds its centre at the cross. There, Jesus bore our sins. There, He cried, “Father, forgive them.” There, justice and mercy met. And there, we find the power to live this prayer.

Ephesians 4:32 says: “Be kind and compassionate to one another, forgiving each other, just as in Christ God forgave you.” That last phrase is key: just as in Christ God forgave you. We forgive, not because others deserve it, but because we didn’t either. We forgive, not because the pain wasn’t real, but because the grace of Christ is more powerful than our pain. At the foot of the cross, we receive mercy – and we are called to extend it.

Living a forgiven and forgiving Life

When we build this prayer into our lives, we become people who are both honest about our sin and confident in God’s grace. We stop pretending. We stop hiding. We live in the freedom of being fully known and fully loved. And when we forgive others, we proclaim the gospel with our lives. We live as signs of the kingdom. We become ministers of reconciliation.

2 Corinthians 5:18 reminds us: “All this is from God, who reconciled us to himself through Christ and gave us the ministry of reconciliation.” We are not just forgiven people – we are sent people. People who carry the grace we’ve received into a world desperate for mercy.

Conclusion

“Forgive us our sins, as we forgive those who sin against us.” These words are both invitation and instruction. They draw us into the grace of God and then call us to give that grace away. So let us pray them daily, humbly, and sincerely. Let us confess freely, receive deeply, and forgive boldly – because that is the way of the kingdom. That is the way of Jesus.
