“Festering” of anger is caused by unforgiveness. Bringing old hurts to new situations is a symptom of unforgiveness. Unforgiveness breeds hate. Forgiveness, “for one’s own sake,” choosing to forgive for the sake of one’s own freedom from resentment and hate, is healing and promotes healing conversations for healing of relationships. One cannot relate well and press forward from insult without forgiveness.
Our world is aflame with hate because of refusal to forgive past insult and deal with the issues of this season and this generation. Those who bring the sins of the parents to peace talks stab old wounds with the bloody knife of old issues. We feed hate, and love dies.
“… You have wearied Me with your iniquities. “I (God), even I, am the one who wipes out your transgressions for My own sake, And I will not remember your sins.” Isaiah 43:24-25 NASB
