How is it that we can't seem to get a long?

What happened to:

"Treat others the way you want them to treat you"
"Don't look at the speck of dust in your brothers eye without first removing the plank from your own eye"
"Look at others as better than yourself"
"Each of you should look not only to your own interests, but also to the interests of others."
"in humility consider others better than yourselves."

We do the complete opposite of these statements! We don't care about others! Every man, woman and child for themselves seems to be our motto.
We judge people around us because of the way they look, act, smell, where they shop, what kind of car they drive or where they go to church or even if they go to church.
We treat others like crap because we think we are better then they are and when people treat us that way we are shocked and surprised!

Do we really think these principles don't apply to us today. Do we think that the principle "you reap what you sow" doesn't really mean what it says?

What is interesting about these principles is that they apply to everyone! It doesn't matter what your religious beliefs are, or where you live, or what color your skin is...the principles work regardless.

So why don't we follow them and why can't we all just get along?
