Your body has many parts—limbs, organs, cells—but no matter how many parts you can name, you're still one body. It's exactly the same with Christ. By means of his one Spirit, we all said good-bye to our partial and piecemeal lives. We each used to independently call our own shots, but then we entered into a large and integrated life in which he has the final say in everything. (This is what we proclaimed in word and action when we were baptized.)
-1 Corinthians 12:12 (MSG)
Whenever we say no to one way of life that we have long been used to, there is pain. But when the way of life is in fact a way of death, a way of war, the quicker we leave it the better.
-Eugene Peterson, A Long Obedience in the Same Direction
