Sensuality is the root behind impurity in the Christian life. We must fight for purity because in turn we are fighting for our Christian walk, our marital relationship, our children, and our friendships. Consequences to sin last a life time, and sin, like adultery, does not happen in a moment, it is a process that we must be able to see and stop. We stop it by relying on the Spirit of God to work in our hearts and minds.
