Bitterness is a silent killer, described in Hebrews 12:15 as a poisonous root. Like any root, it begins unseen, but it doesn’t stay hidden for long. It grows, embeds itself, and eventually bears fruit—fruit that troubles and corrupts not only the person harbouring it but also those around them.
Bitterness is toxic. It does not harm your offender; it harms you. Holding onto bitterness is like drinking poison and expecting someone else to die. It entangles your thoughts, emotions, and relationships, growing deep into your life and becoming harder to uproot with time. This is why Scripture warns us to identify and uproot bitterness before it grows out of control.
The fruit of bitterness corrupts many. It damages relationships and creates an atmosphere where sin thrives. A bitter person may:
. Push others away with negativity.
. Provoke frustration and anger.
. Influence others to act dishonestly to avoid conflict.
Bitterness also leads to unforgiveness, which blocks you from receiving blessings from God. Proverbs 17:22 reminds us, “A cheerful heart is good medicine, but a broken spirit saps a person’s strength.” Bitterness literally dries the bones, which can affect your health. The bone marrow is where blood is made, and when the bones are “dry,” the quality of blood can be compromised, leading to sicknesses, even serious ones like cancer.
When God commands us to forgive others as we have been forgiven (Matthew 6:14-15), it is for our good. Forgiveness is not about letting the offender off the hook; it’s about setting yourself free from the destructive effects of bitterness. God, in His love, doesn’t want you to suffer emotionally, spiritually, or physically from the weight of unforgiveness.
Not only does forgiveness free you, but it also restores your relationship with God. Jesus emphasised this in Matthew 6:15: “But if you refuse to forgive others, your Father will not forgive your sins.” This ultimatum is not meant to harm us but to protect us from the destructive effects of bitterness and unforgiveness.
When you surrender bitterness to God, He replaces it with His peace and love, enabling you to reflect the fruits of the Spirit—love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control (Galatians 5:22-23).
Let us examine our hearts and deal with bitterness quickly, choosing to be fruitful in the things of God. Uprooting bitterness ensures we carry fruit that blesses others, not poison that destroys.
