And from a non-religious perspective you should as well
I think im quite a forgiving person, but i would forgive because it was the "Christian" thing or "right" thing to do, however ive come up with this reasoning (more logical) to why we should forgive.
There are two main points to this theory...
ONE.
If someone is genuinely sorry for their wrongs you should forgive? since why obviously regret their doings, and everyone makes mistakes, and if they are truly sorry it means they feel bad for what they've done and they have been punished enough. If they are sorry it means the put your relationship over their pride, and forgiveness only seems fair?
TWO.
This part of the theory is slightly more complex
What if they DON'T ask for your forgiveness? - you still forgive?
Because everyone has a conscience that tells us whats rights and wrong, if someone has done the wrong thing and doesn't feel they are in the wrong is it REALLY their fault? Its like blaming a child for doing the wrong thing, when they didn't know the rules to being with. So if these people do not see how they are wrong and ultimately have no conscience, can we really cast them outsiders? because they simply do no possess empathy and compassion? not that im recommending you to make them your best friend , but we still should forgive their wrongs, like all people should
So go into the world and forgive :)
Because if you do not forgive, your holding onto the past, and you're past will forever be your future.
