Christ, the DNA of the Believer, the Church

Had a thought along the lines of biology, let's see where it goes. It is from the DNA that a thing is a thing. That a thing grows, repairs itself, matures, etc... It is because of the DNA that a body recognizes friend or foe.

Each cell in a body constantly goes back to the DNA for all it's activity (yes, I know the mitochondria is a little different, let's not quibble over small matters). Cells that do not die, becomes diseased or worse become cancerous. They do not have the same DNA, they are looking at something else, something that is similar but corrupted. It is a pseudo-DNA, a replacement for the real DNA.

If a cell does not go back to the real, it will go back to something. A replacement...an idol perhaps?

It's a metaphor, and a good one for the believer as well as the church, no?
