Avoiding Bitterness in Relationships and Marriages

Reading Time: 2 minutes

Bitterness is a slow killer. It does not always start with shouting or anger; sometimes it begins with quiet silence, a hurt tucked away, a memory you replay in your head. But as days pass, that hurt grows roots. And if left alone, those roots become chains.

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. Hebrews 12:15 (NIV)

Jesus warns us in Luke 12:58 to “try hard to be reconciled on the way.” It is a reminder that if we do not deal with offenses quickly, they become heavier, harder, and more destructive than they were at the beginning. What could have been settled with a conversation ends up becoming a wall between two hearts. That is how many relationships collapse — not because of huge betrayals, but because of small unresolved hurts that were left to fester.

So how do we truly avoid bitterness?

1. Guard your heart early.

Every relationship — whether friendship, courtship, or marriage — will come with offenses. People will say things they should not, or fail to meet your expectations. That is life. The danger is not in the offense itself, but in allowing it to sit in your heart. The longer you hold it in, the more it reshapes the way you see the person. What was once love and trust can quickly turn into suspicion and coldness. Guarding your heart means being intentional about not letting every wound linger there. Protect what flows from it.

“Above all else, guard your heart, for everything you do flows from it.” – Proverbs 4:23

2. Choose reconciliation over silence.

Many people think silence solves problems, but in reality, silence often buries them alive. And buried issues never die — they grow. In relationships, especially close ones, bitterness often comes from the words never spoken, the apologies never given, and the conversations avoided. Choosing reconciliation means being willing to face the discomfort of difficult conversations so that peace can be restored. Silence feels easier in the moment, but it only pushes hearts further apart.

“If your brother or sister sins against you, go and point out their fault, just between the two of you.” – Matthew 18:15

3. Forgive again and again.

Forgiveness is not a one-time event; it is a discipline. There will be times in relationships when you forgive for small things — a careless word, a forgotten detail. And there will be bigger things too. Forgiveness does not erase the wrong, but it stops the wrong from poisoning your heart. Refusing to forgive makes you a prisoner of your own pain, but forgiving sets you free to love without bitterness. Real love cannot survive without constant forgiveness.

“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
