One Bible story that stuck with me ever since I was a kid is the story about Peter asking Jesus how many times he should forgive someone who has sinned against him. Jesus first replies with what would seem to be an absurd number of times – "seventy times seven" – and then He follows with a parable about forgiveness (Matthew 18:21-35).

Hearing this story as a child, I thought, "Man, 490 times? That's a lot of forgiving!" But, that's the point, isn't it? We are to never stop forgiving. And Jesus makes the point very clear that unless we forgive others, our Father in heaven will not forgive us. (Matthew 6:14-15, Mark 11:25)

But, you may be thinking, "What if your spouse does something unforgiveable?" Jesus never said forgiving would be easy. But, He did say that we need to forgive, over and over again. There was no caveat that said to forgive only when the other person deserves it or to forgive if they ask for forgiveness. Matthew 6:15 says, "If you do not forgive men their sins, your Father will not forgive your sins." This is serious business.

In his book The Purpose Driven Life, Rick Warren says:
"Many people are reluctant to show mercy because they don't understand the difference between trust and forgiveness. Forgiveness is letting go of the past. Trust has to do with future behavior.

Forgiveness must be immediate, whether or not a person asks for it. Trust must be rebuilt over time. Trust requires a track record. If someone hurts you repeatedly, you are commanded by God to forgive them instantly, but you are not expected to trust them immediately, and you are not expected to continue allowing them to hurt you.

Forgive, detach and continue to focus on you. Do not let her behavior destroy your inner peace. Forgive her not because she deserve forgiveness. But because you deserve Peace.
