Do you despise the riches of His goodness, forbearance, and long-suffering, not knowing that the goodness of God leads you to repentance? Romans 2:4 NKJV)
Repentance includes physically turning away from sin, and also includes a mental or intellectual change in the way you view sin. When you repent of a certain sin, you agree with God that what you did was wrong. Therefore, you willfully choose to step away from sin.
Repentance is not an emotional act. However, it does involve your emotional well-being. True repentance surfaces feelings of both remorse and regret over the obvious breach you have allowed to invade your life. Sin separates you from fellowship with God, while repentance restores your intimacy with Him.
Some Christians think they can enjoy the security of being saved by God’s grace while living life with a sinful vengeance. But true salvation denotes a humble spirit and a repentant heart. There is no way to live a victorious Christian life while coveting sin. Ask God to help you come to grips with any sin in your life. His restoration is always available through repentance.
