Why would they want to be saved, only to live in disobedience to the very one who saved them? When someone gets born again, they become a new creation, and the old spirit that wanted to commit homosexuality is dead. Now they want to know and serve God, not live a selfish life of sin. My friend was a homosexual, and then he got born again. Even though he still struggled with homosexual feelings, he didn't have sex with another man after he was saved. The problem was, he got HIV while he was a homosexual, and died from AIDS after about 8 years. The good news is he is in heaven, because he loved God more than his desires to continue having a homosexual relationship. If your wife is truly saved, she should seek to be delivered from the spirit of perversion, which is the root cause of homosexuality. Homosexuality is an abomination to God, and Jesus said in John 14:15 that if you love Me, obey My commandments. Those commandments He is talking about are the 2 great commandments of love; to love the Lord your God with all your heart, and with all your soul, and will all your might. The other is to love your neighbor as yourself, and to commit a homosexual act with your neighbor ( which is anyone, not just the person next door ), is to bring them into bondage instead of loving them with God's love. So, if your wife truly is born again, she shouldn't want to continue being a bi; she should want to please God by being an example to other homosexuals that they can be set free. Romans 10:8-10 is how anyone can be born again.
