God’s Word speaks to this by example and precept. First, God made a woman for Adam (Genesis 2), not a man. He blessed the union of a man and a woman. Homosexuality was never God’s plan for marriage.
Later, the law of God put into precept what was true by example. All forms of homosexuality are sin and an abomination to God (Leviticus 18:22, 20:13; Romans 1:27). The current drive for recognition of same-sex “marriages” is a frontal attack on the family that we must resist.
