Is adultery really a sin?

Jesus said in Matthew 21:31, “Verily I say unto you, That the publicans and the harlots go into the kingdom of God before you.”

Jesus was trying to tell men that it really does matter where and when they use their penis. Even the prostitute with whom they had intercourse the night before just might enter the kingdom of heaven before they do. Around the world, the responsibility is placed upon women – she is referred to as a whore and a harlot. Many have been stoned to death. But what do we call men that are unfaithful – the ones that used the prostitute or harlot for their own pleasure? These men go on as though nothing ever happened. One thing about it, God knows about every woman with whom a man has had intercourse. He also knows about every man that has had a sexual relationship a woman. I will explain this more fully in the book.

God did not create a woman so that men can use her body as they wish. He created the woman to be the mother of his children.
