INCEST FORBIDDEN
"None of you shall approach to any that is near of kin to him, to uncover their nakedness: I am the LORD" (LEVITICUS 18:6).
Ammon, the first son of King David, fell prey to the sin of incest due to his lust towards his half-sister, Tamar, and the ungodly advice of his friend and cousin, Jonadab. He lost his life later as a result. Heathen nations like Egypt and Canaan practised these obscene acts of committing immorality with near relations - a practice God forbids.
His emphasis here: "I am the LORD", shows His complete ownership of Israel by creation and redemption. He had become the God and Father of Israel. So, He instructed them to avoid this unwholesome and despicable act as they were going to inherit the Promised Land. Keeping and obeying God's judgments and statutes form a major part of His covenant with Israel and the Church. Sexual sins - formication, adultery, incest, rape and pornography are potent tools in the hands of Satan in leading many souls to hell. Lust of the flesh has done so much harm to fallen man that even some strong men have fallen victims.
Men like David, Samson and Solomon brought disrepute and a dent to their otherwise excellent ministries as a result of this sin. Believers are warned to keep away from the strange woman and not to fumble in immorality with any member of the family or relations - close or distant. The antidote is to be watchful and desist from unholy intimacy with the opposite gender. Some, out of a genuine desire to help someone, get tempted and fall. The devil cares less about the sincerity of such a person as long as he can get him down. Fleshly lusts war against the soul and drown men in perdition. The righteous must be careful to abstain from it to avoid eternal regrets.
Keep your body under by bringing it into subjection.
