I once heard a minister give the following message in a sermon.
1) The bible does not, as many parents think, teach that masturbation is a sin. The sin was that God told the man, "give your brother's widow a child," and the man had sex with the widow, but "spilled his seed on the ground" to prevent the conception of a child. It was not masturbation. It was "early withdrawal," and the sin was that the man directly defied God's command.
2) Mothers, your boys are sexual beings, with instincts given to them by God. Better he shut his door and stain his sheets than that he get the girl next door pregnant.
3) Yes, looking at a woman with lust is wrong. Stopping masturbation is not going to stop lust. They are not necessarily the same thing.
The congregation was shocked, but the attendance of young people at church sky rocketed.
