Nothing in the Gospels suggests that God does not forgive the sins of those who are well disposed and who ask to be re-embraced.
But God’s grace, so abundant, is always demanding. Those who have received so much must learn to give so much too, and not to hold back only for themselves what they have received. Those who have received so much must learn to give so much. It is no coincidence that the Gospel of Matthew, immediately after giving the text of the Lord’s Prayer, among the seven expressions used, emphasizes precisely that of fraternal forgiveness: “For if you forgive other people when they sin against you, your heavenly Father will also forgive you. But if you do not forgive others their sins, your Father will not forgive your sins” (Mt 6: 14-15). This is important! I think: sometimes I have heard people say: “I will never forgive that person! I will never forgive what they did to me!”

On the path towards forgiveness, we often meet a few of our nemeses, and the most prominent one is anger. Perhaps that anger within has been instilled in us following a lineage of retaliatory thought patterns dating back 3000 years. -- huddlehumans.com
