The Bible's view of sex education is God's work on humans since creation. Equipped with the sexual organs, sensual feelings are given to man as a blessing to be enjoyed in marriage. On the other hand, the mandate is to be active in creation (procreative) by procreating through sexual intercourse. A man leaves his mother and father united with his wife as one flesh, both naked but not ashamed, to enter into an intimate relationship that can only be experienced through sexual intercourse. These are the things God aims for sexual relations in marriage. Sex is something sacred as God instituted the first marriage in Eden. Therefore the Bible clearly condemns the practice of unholy relationships in marriage. On the other hand, Christian family couples are invited to carry out sexual relations in the household according to the divine will. Sex education can be related to the doctrine of holiness as the foundation of Christian faith as follows: First, the need to develop holiness education in schools, seminars, and in churches in order to clarify the position of sexual sinfulness that is committed outside of marriage.The Bible's view of sex education is God's work on humans since creation.
