Body of Grace
I've been told that the human body is constantly replacing its own cells. In fact, after about seven years every skin cell has been replaced at least once. It would sure be nice if those cells came in young and unblemished. But no, when a new cell is born into the body, it takes on the likeness and history of that body. It's all part of the genetic code that runs through every one of us.
Like the human body, the Body of Christ is constantly taking on new members. And just as the genetic code inside of a physical cell determines the identity of that cell, Christ's life running through His Body, the church, is what determines who we are.
Now that's an amazing thought, but it's true! Christ's life is our source of life, and what He has done on our behalf, we can experience as a part of His body.
