When a man or woman commits adultery, what kind of a sin do they commit? First of all, they sin against themselves. First Corinthians 6:18 says, “Flee fornication. Every sin that a man does is without the body; but he that commits fornication sins against his own body.”
That means there is something absolutely unique about the sin of immorality. There is no sin more harmful spiritually, mentally, physically and emotionally than the sin of adultery.
Monogamous marriage, one man for one woman, was given by God for the protection and development of the deepest psychological, physical, and spiritual needs of humanity. Marital fidelity is the glue that holds the family together, and the family is the core of society. Now you can understand why Satan has leveled his fiery darts against the home through sexual immorality.
