When Jesus spoke of man’s corrupt, sinful nature He always addressed it in its ultimate result. For example, Jesus never warned us that we must not covet because it might lead to stealing…He said rather, You must not covet because it is stealing. The same goes for all the fleshly appetites and passions that come from our human nature. If you think it – Jesus says you’ve already done it in your heart…from lust to murder. For anytime we allow fantasy to fill our mind instead of truth, our flesh is winning.
Within us is an ever raging battle…sometimes with one side winning, sometimes with the other. The battle is between our flesh and the Holy Spirit. It was fine before we were Christians…there was no need for any kind of battle…we just did what we wanted. But now that we live by the promptings of the Holy Spirit within, the conflict has started. What do you have your mind set on? It tells us in this verse that you’re either devoted to your corrupt sinful nature…or you’re mindful of the Holy Spirit. So how can we change this cycle? It says in Galatians 5:16, “So I say, live by the Spirit, and you will not gratify the desires of the sinful nature.” Living by the Spirit is listening carefully, reacting immediately, and obeying promptly.
