RE: Why is it a sin to be gay?

More evidence from Genesis 2:22-24, ”And the rib that the Lord God had taken from the man he made into a woman and brought her to the man. Then the man said, “This at last is bone of my bones and flesh of my flesh; she shall be called Woman, because she was taken out of Man.” Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh.”

God made marriage and intended on humans to reproduce because no reproducing is not spreading the word of god
