Is Forgiveness Limited

How often must we forgive people? Are we expected to be gullible victims? Jesus taught about forgiveness, but how often must we be abused and bruised by others and still forgive? That is essentially Peter's question in Matthew 18:21, “Lord, how often shall my brother sin against me, and I forgive him? Up to seven times?” Ancient Jewish teaching could have suggested with forgiveness, 3 strikes and you're out. So, Peter's suggestion of 7 times, may have seemed quite generous to him. A question in response to Peter might be, how often ought we imitate God's forgiveness? If the answer is only 7 times, then we are all in trouble.
