Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh.Genesis 2.24
The Lord was witness between you and the wife of your youth, to whom you have been faithless, though she is your companion and your wife by covenant.Malachi 2.24
God’s general purpose* for people is heterosexual, monogamous marriage.
The Bible tells us when two people of opposite sexes are joined together in marriage, there is a bonding, a new togetherness, an emotional attachment and a mysterious oneness.
Once you are married, you no longer live just considering yourself; there is a new bond with your spouse.
Sexual oneness demonstrates and evidences this oneness of marriage.
It is extremely dangerous, therefore, to be sexually active before marriage; the emotional baggage simply piles up.
This will sound very strange to most people today.
