Why not Love Them?

This evening a very profound thought was put into my head and I have been mulling it over in my head ever sense. I think I will approach the subject from a young persons point of view, and the spring board so to speak, will start with another subject that has been discussed in our Bible Study....the subject of partiality.
This is a very large problem in our churches and I know that it doesn't all start with us young people. So often our parents taught us, but that is not and never should be an excuse. We look at someone and size that person up in two seconds, and decide whether we will like them or not, and more often than not we are wrong, so wrong about that person. We put signs above their heads, announcing to ourselves and others around us that this person is this or he's that, without even giving them a chance to prove to us who they are. Or how about this one....we know them but they make a mistake, or a stupid decision, and what do we do? We tear them apart and hack them to pieces like a butcher does a pig. And what gets me is, even after they repent and attempt to move on we keep doing it. We keep beating away and hacking at them until they are no more then ground up hamburger. I don't understand it. What part of "forgive us our trespasses, AS WE FORGIVE THOSE WHO TRESPASS AGAINST US"...do we not understand? Or this one; “For if you forgive men their trespasses, your heavenly Father will also forgive you." Doesn't that insinuate the fact that if we don't forgive others, GOD wont forgive us? That should scare us my friends. Forgiveness is a very important thing to GOD. I mean think about it, GOD sent Jesus to earth to die for us....your like; 'yeah...I learned that when I was 2'... but how's this; Jesus had a choice. In the garden GOD revealed to him exactly all he was going to suffer and all that that suffering entailed, and he was left with a choice. He didn't have to die for you and for me. He didn't have to go through with it. All that pain, misery and rejection, not to mention his separation from his Father, and then on top of that he got a free train ride to Hell. He had never committed a sin and here he was becoming sin itself and being punished for ALL (not just some) of the sins ever committed and the ones that hadn't/haven't been committed yet. He had a choice. He didn't have to do it, but he did, and he did it for you and me. That is why forgiveness is so important him. He made the ultimate sacrifice so that we could be forgiven. 
You know those people in our churches that we can't get along with, or that are "bad influences" on us?...we're gonna spend all eternity together. It doesn't make a bit of sense to all 'hate' each other now and then talk about how awesome heaven is going to be. Heaven is going to be made up of people, and many of those people are going to be those people we refuse to associate with. The ones we pre-tag, the ones we don't click with, or don't see eye to eye with. The ones who in our eyes don't dress right, talk right, act right or look right. We're gonna spend eternity with them. Why not love them now?
