We must not make the mistake of thinking that just because we get saved and receive salvation that everything will be smooth sailing from that day on. Your flesh is the part of you that served the devil; it will always crave things that it doesn't need. There will always be a war between your flesh and your spirit. The flesh doesn't want to be controlled by the spirit, it wants to continue to lust after the things of the world. If we will deny our flesh, we will become a conquering hero!
