If we are the body...

We are all part of the body of believers (those who are believers in Christ), and as such we are a family that is closer than blood relatives. We have something that goes beyond mere lineage. We have a direct spiritual link to Christ and are co-heirs with him. Doesn't that just blow your mind?? But with such a connection to one another, we have the responsibility of supporting, encouraging, and aiding one another at all times. How is it that we as Christians bicker and tear one another down more than any other 'group' of people? No other 'religion' -- or faith if you will -- has so many divisions in the church. The fact that we have so many denominations says a lot. Sure, we're "Protestant," but there's a whole slew of denominations under that name. Even other religions don't have so many divisions. There are two commonly recognized splits -- orthodox and traditional -- and I feel like they mean the same thing.
The point is, that we are one body (1 Cor 12), and as such we must act as one body to bring glory to God. That's our purpose. Our purpose isn't to glorify self -- to see to our needs and wants -- but to work as a mighty unit to bring glory to God. He knows that we are all fallen creatures and have the innate tendency to sin. But this is where, in our weakness, we can show the world his magnificence! Imagine, hundreds and thousands and millions of people -- all of whom are set up for failure through sin -- defy that innate tendency in order to bring glory to God! It is HE who brings us together if we let Him.
I can't say it any better than Christ Himself, so I'll close with these verses:

Romans 15: 5-7 (NIV)
"May the God who gives endurance and encouragement give you a spirit of unity among yourselves as you follow Christ Jesus, so that with one heart and mouth you may glorify the God and Father of our Lord Jesus Christ. Accept one another, then, just as Christ accepted you, in order to bring praise to God."
