Does God approve of same-sex marriage?

YES!

1 Corinthians 6:9-11 says, "Don't you realize that those who do wrong will not inherit the Kingdom of God? Don't fool yourselves. Those who indulge in sexual sin, or who worship idols, or commit adultery, or are male prostitutes, or practice homosexuality, or are thieves, or greedy people, or drunkards, or are abusive, or cheat people-none of these will inherit the Kingdom of God. Some of you were once like that. But you were cleansed; you were made holy; you were made right with God by calling on the name of the Lord Jesus Christ and by the Spirit of our God."

God can, will, and does forgive the sin of homosexuality. All you have to do is call on His name and ask for forgiveness.

A comment: the Word "homosexual" was created in the 19th century. It does not occur in The Bible. Any translation of the text that uses the Word is therefore distorting the original. A number of religions do not consider homosexuality a sin.

Homosexual acts should not be considered a sin. Accepting that people can be attracted to the same sex but not allowing them to commit the physical act of love is basically saying "it's O.K. to be gay, you just can't be gay." If the physical act of love defines our sexuality then saying it is wrong for homosexuals to have sex is basically saying "suppress your sexuality." You can be attracted to the same sex but you must NEVER act on that attraction. Basically you have to pretend those attractions don't exist. It's denying them a sexuality.

Answer:

God will forgive any sin repented of.

Paul wrote: "Let him that stole steal no more..." (Eph.4:28). It's true of the other nine sins of breaking God's Ten Commandments also.

Homosexuality is perverse adultery... and is forgivable if repented of, departed from, and mercy and forgiveness sought of the Lord.
