Yet, He was without sin. As we trust completely in Him, we can experience victory - His victory. There are two distinct characteristics of the life that experiences victory over lust. One is deeply spiritual. The other is very practical.
Lust begins in the heart, but is consummated with physical actions.
The Bible describes David was a man after God's own heart. He loved God and trusted in Him alone. However, David yielded to the lusts of the heart in the latter part of his life and became defeated. His lust led to adultery and even murder. The sins and crimes of David were conceived in his heart on a roof one evening.
