The apostle Paul recognized the fact there is an internal battle within each one of us; every believer has an “enemy within” that we must fight. This lifelong battle between the flesh and the Spirit will rage until our death. Romans 7:21–23 addresses the enemy within: “So I find this law at work: Although I want to do good, evil is right there with me. For in my inner being I delight in God’s law; but I see another law at work in me, waging war against the law of my mind and making me a prisoner of the law of sin at work within me.” Paul understood that his fleshly nature would never conform to God’s will. No matter how much he might want to obey God in every way, he was fighting the “evil . . . right there with me,” the enemy within.
