A thought about forgiveness, from our study at the end of Genesis– if we give in to the desire to punish those who have hurt us, out of a sense of justice, we will never be satisfied. The just punishment of sin is eternal death, and only God can inflict that. So we will never punish others enough for our innate sense of justice to be satiated, and we will do a great deal of damage to others and ourselves in the process, because we are not God. Leave punishment to God, and let Him be as merciful as only He can be.
“Vengeance is mine, says the Lord. I will repay.”
