My take on things like this: forgive and forget. I myself do that in a very short amount of time. Also, do not hold grudges, because as time goes on, your hate of that person will I crease. Speaking of hate, do not do that either. Throughout most if not all of my life up to this point, I have not hated another person even when they wrong me. I also say respect other's beliefs (I.e religion and politics). Wouldn't you like your beliefs respected? I would guess yes. This also goes towards trying to overly convert someone to our faith. If they don't want to be Christians, don't ask them over and over again, don't spew Bible verses out at them (since when is anybody really impressed that you know a couple of words from a boo), and actually practice the faith (being more like Christ). Lastly, no judging (or at least, negative judgement).
P.S. this is basically my introduction to who I am post. Have a great day!
