Again I say to you, if two of you agree on earth about anything they ask, it will be done for them by my Father in heaven. For where two or three are gathered in my name, there am I among them.” Then Peter came up and said to him, “Lord, how often will my brother sin against me, and I forgive him? As many as seven times?” Jesus said to him, “I do not say to you seven times, but seventy-seven times. – Matthew 18:19-22
The most difficult math problem in the universe, it turns out, is 70 x 7. Perhaps the hardest thing to do in the Christian life is to forgive someone who has hurt you, often badly…
When we forgive, we are confessing that vengeance is God’s (Rom. 12:19). We don’t need to exact justice from a fellow believer because justice has already fallen at the cross. We don’t need to exact vengeance from an unbeliever because we know the sin against us will be judged in hell or, more hopefully, when the offender unites himself to the One who is “the propitiation for our sins, and not for ours only but also for the sins of the whole world” (1 Jn. 2:2).
A prisoner of war who forgives his captor or a terminated pastor who forgives a predatory congregation, these people are not overlooking sin. Nor are they saying that what happened is “okay” or that the relationships involved are back to “normal” (whatever that is). Instead they are confessing that judgment is coming and they can trust the One who will be seated on that throne.
You don’t have to store up bitterness, and you don’t have to find ways of retaliation for what’s been done to you. You can trust a God who is just.
