Forgiveness is divine and, as such, proves difficult for the carnal human nature. But forgiveness is required for the maintenance of God’s favor in our lives. When we struggle to forgive, we should ask God for grace and more grace until our hearts have completely let go. Also, when we see others struggle, we should pray God’s grace upon them rather than judge.
Then his master, after he had called him, said to him, ‘You wicked servant! I forgave you all that debt because you begged me. Should you not also have had compassion on your fellow servant, just as I had pity on you?’ And his master was angry, and delivered him to the torturers until he should pay all that was due to him. “So My heavenly Father also will do to you if each of you, from his heart, does not forgive his brother his trespasses.”
— Matthew 18:32–35 NKJV
