pc10 Sexual Purityis an exhortation to purity in sexual matters for the Christian. We look at various aspects of the issue.
Topics: It is not an impossible fight! | The Biblical Model | Homosexuality and Prostitution | Nudity and the Mind | Self-Stimulation | Resisting the Temptation.
Excerpts: Job 31:1 I made a covenant with mine eyes; why then should I think upon a maid? Job understood that sexual sin begins with the sight, and the seeing before desiring. Job made a covenant with himself, a commitment that he would not look on young women to desire them or to let his imagination run wild with them even their image or in his thoughts. Equally, Jesus taught us in Mat. 5:28 that even thinking sinful thoughts without doing them is as sinful as actually doing them. This is an amplification of Exo 20:17 “Thou shalt not covet thy neighbor’s wife”. David saw before taking (2Sam 11:2).
Fasting is to teach us that the body does not control over us, and this is exactly what is necessary for people with this problem. This sin is pinned to the thoughts, “for as he thinketh in his heart, so is he” Pro 23:7. “I can do all things through Christ which strengtheneth me” Phil 4:13.
