It's a lot easier to forgive than it is to forget. I have forgiven a lot, but I've never forgotten!
I try to look for the best in people. But, if you wrong me once shame on you, if you wrong me twice, shame on me!
Being a Christian definitely makes it easier to forgive, but unfortunately, some people commit the same sins time and again and don't learn from their mistakes. That makes it difficult to forgive. You can only hear "I'm sorry" so many times. If a change isn't made, then the words mean nothing.
