We've all heard this. God wants us to avoid fornication because it is sin. That may sound strange, for that's no reason to avoid premarital or extramarital sex for non-Christians. Apart from the sin, there still are reasons to avoid fornication. One reason for sexual purity is to avoid AIDS, herpes, and other dreaded diseases.
Fornication causes emotional wounds, and troubles in marriages.
Think of the shame that accompanies unfaithfulness to one's husband or wife, or that comes with premarital sex. But for the Christian, the main reason is that Jesus Christ forbids it. This grieves the spiritually-minded Christian. Parents ought to teach children to fear fornication as they fear any imaginary monster. Their children must know about the deceit of fornication, the allure of fornication, the power of fornication, the destruction of it.
