The Poison of Unforgiveness

Matthew 6:14 – “For if you forgive men their trespasses, your heavenly Father will also forgive you.”

Poison is defined as a substance that, through its chemical action, harms or destroys an organism. In the same way, unforgiveness is a spiritual poison—one of the most destructive tools the enemy uses against God’s people. It doesn’t just affect the soul; it can manifest in mental and even physical ailments such as depression, anxiety, and health conditions like arthritis or high blood pressure.

What is Unforgiveness?

Unforgiveness can be defined as holding a grudge against someone who has wronged you or refusing to show compassion and extend forgiveness. It’s a sin that clouds judgment, fuels bitterness, and leads to harmful actions.

A powerful biblical example is found in the story of Esau and Jacob. Jacob deceived their father and took Esau’s blessing, an offense that caused deep resentment in Esau’s heart. Instead of forgiving his brother, Esau harbored hatred and plotted revenge. Genesis 27:41 tells us:“Esau held a grudge against Jacob because of the blessing his father had given him. He said to himself, ‘The days of mourning for my father are near; then I will kill my brother Jacob.’”

Like Esau, we often feel justified in our anger and resentment. However, God commands us to forgive just as He forgives us. Matthew 18:33 reminds us:“Shouldn’t you have had mercy on your fellow servant just as I had on you?”

The Consequences of Unforgiveness

The Bible warns that disobedience, including a refusal to forgive, can have serious consequences. Deuteronomy 28:58-61 describes how Israel faced sickness and hardship when they turned away from God’s commands:“If you do not carefully follow all the words of this law... the Lord will send fearful plagues, severe and lingering illnesses… He will bring upon you all the diseases of Egypt that you dreaded, and they will cling to you.”

Though Jesus came to redeem us from the curse of the law, we must still choose to walk in obedience. John 15:12 declares:“This is My commandment, that you love one another as I have loved you.”

Love: The Antidote to Unforgiveness

Love and unforgiveness cannot coexist. Bitterness, envy, hatred, and pride all stem from an unforgiving heart. But when we embrace God’s love, we are empowered to forgive, let go of resentment, and walk in freedom.

Unforgiveness binds, but love liberates. Next time, we’ll explore the deeper effects of unforgiveness and how to overcome it through God’s grace.
