The greatest battle a Christian will ever fight is not against an external enemy but against themselves. Revelation 12 describes a war that began in heaven, and it reveals two very different ways of fighting: the way of Michael, and the way of the accuser. Those who are truly yielded to the Holy Spirit make war with themselves, while those who cling to sin redirect that energy outward, finding fault and accusing others. The story of Cain and Abel illustrates two classes of people that will exist until the end of time. Cain came to God on his own merits, with no genuine sense of need, while Abel came by faith, recognizing his need for a Savior. The question for every Christian is not whether we obey God, but why we obey Him. A sense of genuine need before God is the very first condition of acceptance with Him, and the closer we draw to Jesus, the more clearly we see ourselves and the deeper that need becomes.
