God’s design for marriage

Since love is from God and God tells us to love one another, why is it a sin for two men or two women to be married and love each other? Why is it a sin for two men or two women but not for men and women to be married to each other?

The Bible teaches that marriage is a union between one man and one woman (Genesis 2:18-24; Matthew 19:4-6). The Bible makes it clear that sexual activity is to take place in marriage (Hebrews 13:4) and that sexual activity between people of the same sex is a violation of his will (Romans 1:26-27; 1 Corinthians 6:9-11).

It is not a sin for a man and a woman to be married to each other because they are in a relationship and institution that God designed. There is no sin when people’s actions line up with God’s will.
