There’s a difference between real and fake Christianity. And this litmus test, given by the Apostle Paul in Romans 8, shows where you stand. Your mind is either: (1) set on the spirit or the flesh; (2) set on life or death; and (3) subject to the law of God or in hatred to it. That’s why there’s no such thing as a “gay” or “thieving” Christian. If you’re a true believer, you will denounce such sins and put them away. You know who you are by what rules you—be it the spirit or the flesh.
