Why Forgiveness Feels Impossible and Why It Isn’t

Is there someone whose name still does something to your chest when it comes up? Someone whose face surfaces in your mind in quiet moments, carrying the weight of what they did? Someone you have told yourself you have forgiven, and yet the wound reopens every time you see, hear about, or remember them?

Forgiveness is one of those things that most people agree with in principle and struggle with in practice. We know we are supposed to do it. We have heard the sermons, read the verses, nodded along in agreement. And then we go home and find the bitterness still sitting exactly where we left it, patient, quiet, and deeply rooted.

This article is not going to tell you that forgiveness is easy. It is not. But it is going to tell you the truth about why it is hard, what God actually did first, what unforgiveness is doing to your body and soul, and the only reason any of us can genuinely do this at all.

We’ll cover:

Let us start not with what God asks of us, but with what He already did for us. Because the call to forgive only makes sense in the light of what we have already received.

Romans 5:8 says something that should stop us in our tracks every time we read it: God demonstrates his own love for us in this: while we were still sinners, Christ died for us.

Not after we had cleaned up. Not after we had tried harder or proved ourselves worthy. While we were still sinners. While we were enemies of God, actively in rebellion, completely without merit, He moved toward us. He sent His Son. He bore the cost of every offense we would ever commit, not because we deserved it, but because that is the nature of His love.

Colossians 2:13-14 describes what happened at the cross in terms that are almost staggering: God made us alive with Christ even when we were dead in transgressions. He cancelled the charge of our legal indebtedness, which stood against us and condemned us. He took it away, nailing it to the cross. Every charge. Every debt. Every sin. Nailed. Gone.

This is the foundation of everything that follows. Before God ever asked us to forgive another person, He forgave us a debt we could never have repaid. He did not ask us to earn it. He did not wait for us to deserve it. He simply, at enormous cost to Himself, extended what we had no right to receive.

Which is exactly what makes the next part so confronting.

“Bear with each other and forgive one another if any of you has a grievance against someone. Forgive as the Lord forgave you” (Colossians 3:13, NIV).

God asks hard things. He asks us to obey when it makes no sense. To trust when we cannot see. To believe when the evidence seems to point elsewhere. And now, to forgive people who have genuinely wronged us, sometimes deeply, sometimes repeatedly, sometimes without any apology or remorse.

These things feel impossible because, honestly, they are. Not in the abstract, but for the natural human heart. Jeremiah 17:9 is direct about this: the heart is deceitful above all things and beyond cure. Who can understand it? 

The natural human heart does not reach toward forgiveness when it has been wounded. It reaches for justice, for distance, for self-protection, sometimes for revenge. That is not a spiritual failure on your part. It is an accurate description of what sin did to our nature.

When Adam and Eve sinned in the garden, what was broken was not just their relationship with God. It was the orientation of the human heart itself. Where we were made to reflect God’s love, generosity, and grace, sin bent us inward: toward self-preservation, toward keeping score, toward protecting what is ours. Forgiving someone who hurt us runs directly against that bent. Which is why we cannot simply decide our way into it.

But here is where the Gospel becomes the most practical thing in the world.

Before we get to the good news, it is worth sitting with what the alternative actually costs. Because unforgiveness does not hurt the person who wronged you. It hurts you.

When you replay an offense, your body responds to the memory the way it would respond to an actual present threat. Your heart rate rises. Cortisol floods your system. Your nervous system goes into low-grade fight-or-flight, and it stays there every time that person’s name surfaces, every time the memory returns. Proverbs 14:30 says a heart at peace gives life to the body, but envy rots the bones. Scripture was describing something physiologically real long before modern medicine could measure it.

Hebrews 12:15 warns to see to it that no one misses the grace of God, and that no bitter root grows up to cause trouble and defile many. Bitterness spreads. It starts as a wound and grows into a lens through which you begin to see everything. It poisons relationships that had nothing to do with the original offense. It hardens the heart in ways that go far beyond the person you are holding it toward. And it builds a wall between you and God, because Jesus is explicit in Matthew 6:14-15: 

“For if you forgive men their trespasses, your heavenly Father will also forgive you. But if you do not forgive men their trespasses, neither will your Father forgive your trespasses” (NKJV).

The stakes of unforgiveness are not small. They reach your body, your relationships, and your standing before God. But knowing this does not make forgiveness easier. It only makes the need more urgent.

Which is exactly why God did not just command forgiveness and then leave us to find our way to it alone.

Ezekiel 36:26 contains one of the most extraordinary promises in all of Scripture: 

I will give you a new heart and put a new spirit in you. I will remove from you your heart of stone and give you a heart of flesh” (NKJV).

God knows we cannot forgive from a heart of stone. So He does not simply issue the command and walk away. He offers to change the very thing that makes obedience impossible. A new heart. A heart of flesh, responsive, tender, capable of things the old heart could never reach.

And He does not stop there. John 14:16-17 records Jesus promising His disciples, and through them, every believer: 

And I will pray the Father, and He will give you another Helper, that He may abide with you forever—the Spirit of truth, whom the world cannot receive, because it neither sees Him nor knows Him; but you know Him, for He dwells with you and will be in you” (NKJV).

The Holy Spirit is not a vague spiritual concept. He is a present, active, indwelling Person whose specific role is to help us do what we cannot do on our own.

Galatians 5:22-23 tells us that one of the fruits the Spirit produces in us is gentleness. Not striving. Not trying harder. Fruit grows when the branch abides in the vine. Jesus says it plainly in John 15:4-5: 

“Abide in Me, and I in you. As the branch cannot bear fruit of itself, unless it abides in the vine, neither can you, unless you abide in Me. “I am the vine, you are the branches. He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing” (NKJV).

This is the answer to the impossibility of forgiveness: you do not do it alone, and you do not do it from the old nature. You abide. You stay close. You surrender the wound to the One who bore the wounds of the whole world, and you allow the Spirit who lives in you to do in you what you genuinely cannot do for yourself. Forgiveness, real forgiveness, is a fruit of abiding in Christ. It is not manufactured. It is grown.

So what does this actually look like, not in theory, but in the life of a person carrying a real wound?

Forgiveness is a decision before it is a feeling. You will rarely feel like forgiving the person who hurt you. The feeling of release, when it comes, often follows the decision rather than preceding it. This matters because many people wait to feel ready before they act, and the feeling never arrives, because the natural heart does not generate it on its own.

Forgiveness is also not the same as reconciliation. You can forgive someone and still maintain boundaries. You can release the debt they owe you without necessarily resuming the relationship. Jesus does not command you to trust someone who has repeatedly shown themselves untrustworthy. He commands you to forgive them, and those are genuinely different things.

And forgiveness is not a once-for-all event, at least not always. Peter asked Jesus in Matthew 18:21 how many times he should forgive someone who sins against him, suggesting seven times was generous. Jesus said seventy-seven times. 

The number is not a limit. It is a direction; keep forgiving. Every time the memory surfaces and the bitterness rises, you bring it back to the cross. You lay it down again. This is the rhythm of forgiveness for deep wounds, repeated surrender rather than a single dramatic moment.

Luke 23:34 shows us Jesus, on the cross, in the worst pain imaginable, saying, “Father, forgive them, for they do not know what they are doing. He did not wait until He felt ready. He did not wait until they asked. He forgave from the place of deepest suffering, not from comfort. That is the model. And He offers us His Spirit so that we do not have to do it in our own strength.

You do not have to have it all resolved this week. But there is somewhere to begin:

  • Name the wound honestly before God. Not a general prayer about forgiveness, but a specific one. Name the person. Name what happened. Bring the actual thing to God rather than a sanitised version of it. He already knows. The conversation is for you.
  • Ask for a new heart, not just more willpower. Pray Ezekiel 36:26 over yourself. Ask God to remove the stone and give you flesh. This is a prayer He answers, because it aligns perfectly with what He already promised to do.
  • Abide before you strive. Before you try to work up forgiveness through sheer effort, spend time in the Word and in prayer this week. The fruit grows from the abiding. Closeness to Christ produces what effort alone cannot.
  • Let the cross be the reference point. When the bitterness rises this week, bring your mind back to Romans 5:8. While you were still a sinner. Before you deserved anything. That is the measure of what you have been given. And that is the measure you are being invited to extend.
  • Release the feeling from the decision. You may not feel forgiving this week. Make the decision anyway. Tell God you are choosing to release the debt, and ask the Spirit to make it real in you over time. He will.

God did not ask you to forgive and then hand you the bill. He paid the bill first, at the cross, at a cost that is still incomprehensible. He forgave you a debt you could never repay, while you were still His enemy, before you had done anything to deserve it. And then He gave you a new heart, and a Spirit who lives inside you, specifically to make possible what the old heart could not.

Forgiveness is hard. It is one of the hardest things God asks of us. But God does not ask hard things and then leave us to do them alone. He changes us from the inside. He abides in us. And as we abide in Him, as we stay close, as we let self die and let Christ live, He does in us what we could never manufacture for ourselves.

The person who hurt you may never apologise. They may never know the weight of what they did. But you were not made to carry that weight. You were made to lay it down at the foot of a cross where it was already dealt with, by the only One who had the right to forgive it all.
