Sin has no place in the life of a believer. When we allow sin to reign in our mortal bodies, we give it the power to control our actions and lead us away from God. The apostle Paul urges us not to obey the evil desires of the flesh, but instead to live according to the Spirit. This requires discipline and constant vigilance, as the temptation to sin is ever-present. However, when we choose to walk in the Spirit, we can resist the desires of the flesh and live in freedom. It is through self-control and a commitment to purity that we can experience victory over sin and live the life God has called us to. God promises that when we submit to His will, we will experience His power to overcome temptation and live in holiness.
