Matt. 5:27-30 Thou shall not commit adultery-God commanded the children of Israel not to commit adultery because it destroys the marriage relationship by dividing the affection of the one committing adultery and destroys the trust of the other marriage partner. However, Jesus said You have heard it said, “You shall not commit adultery. But I say to you that everyone who looks at a woman lustfully has already committed adultery with her in his heart” It is not the act of adultery that destroys the marriage relationship but the lust that precedes the act itself. When someone lusts after another, they have already set in motion the thoughts that lead to the act and even if they never commit the act itself, they have already violated their marriage vows to love only their spouse by fostering love for someone outside the marriage in their heart.
