"It is the spirit who gives life; the flesh profits nothing. The words that I speak unto you are spirit, and they are life" (John 6:63). Jesus said there is spirit life in the spoken word. That's why it is important for us to confess what God has already said about us in His Word. Words carry spiritual forces. Words can transmit fear or words can transmit faith. They transmit images after their kind to others. God's Word transmits the image God wants you to have. The devil's words transmit the image he wants you to have.
I know this is the right thing to do, and I want to do it. I just can't make myself do it! In fact, I fall back into doing the wrong thing!!! (Romans 7:15) Most of us have been taught that transformation is an information problem. Learn the right principles, apply the right rules. Study the right theology. Hear the right sermon. Think better thoughts, add a little discipline if you have to. Fix the argument and the behavior will follow. It won't, and it doesn't. Not because the information is wrong — but because information doesn't reach the place where your life is actually governed.
Romans 8:31 contains a powerful rhetorical question and I encourage you to memorize it. Unfortunately, there are still some believers today wondering, "Is God really for me?" Well, my friend, the Word of God does NOT say "maybe God is for us" or "hopefully, God is for us." It simply says, "If God is for us, who can be against us?" Indeed, when God is for you, what opposition can succeed against you? When God Himself fights for you, defends you and vindicates you, what adversity or adversary can stand against you? There are none! Hallelujah!
