God has called us to Himself, and He has elected us to spend eternity with Him. There are things that battle against our calling and election. The Christian has three main enemies, which are: the flesh, the world, and the devil. In fact, the strongest and greatest enemy of a Believer is the flesh. Though his spirit is willing to please God, yet his flesh is weak. And if you want to succeed in the race you are running, then you must bring your flesh under subject to your spirit and obey God's Word and His Spirit.
