Jesus is the Christ: Believing That, You May Have Life in His Name
Any teaching that will lead us away from the saving power of Jesus as the Christ will lead us to our own flesh. It will bring about a self-imposed worship of the same flesh and sever our connection with the Head (Col 2:16–19). The devil does not care what we believe and how we live, as long as we do not believe and live lives that proclaim Jesus as the Christ of God (cf. 1 Jn 2:22).
When we battle our flesh and its desires with our own flesh, then the devil has what he desires, because he is devouring us as our enemy (1 Pet 5:8). If we want the eternal life God has promised and victory over this world, we can find it in His Son, Jesus the Christ (1 Jn 5:1-4)!
