When it comes to the Bible, the moral law from the Old Testament did not change in the NT and is still relevant even in our times. God does not create anyone ''gay'' or homosexual. It is a choice and is possibly psychological in nature. As for Sodom, yes, it was destroyed because of homosexuality that was the top thing besides all the other sins mentioned. As for loving others yes, we do need to do that, but when God says something is a sin, it is a sin. Love the sinner but hate the sin. As Christians we are called not to be
of the world but in the world and to follow God's commandments including loving others. As for the ceremonial law which had to do with piercings, hair, and food that was for a time and if you do not want to follow that part it is fine. But, the moral law remains the same. Paul talks about homosexuality being sinful in Romans 1:24-28, Peter talks about it being sinful in 2 Peter 2:4-10, even Jesus talks about Sodom and Gomorrah in Matthew 10:15, etc. Scripture interprets scripture. A final verse I will mention is in Jude.
Jude 1:6-7
"And the angels who did not keep their positions of authority but abandoned their proper dwelling---these he has kept in darkness bound with everlasting chains for judgment on the great Day. In a similar way, Sodom and Gomorrah and the surrounding towns gave up to sexual immorality and perversion. They serve as an example of those who suffer the punishment of eternal fire."
You may have these thoughts, but they are unnatural. I have had thoughts about men (twice or thrice), but just because someone has those thoughts does not mean that one is homosexual, bisexual, etc. When you have these thoughts, rebuke them in the name of Jesus, listen to some music that keep these thoughts from causing you to think strange, read your Bible and focus on it, ask believers to pray for you, and give these thoughts into God's hands. For resources on this I recommend Exodus International (
www.exodusinternational.org) Living Hope Ministeries (
www.livehope.org), and also a video that you can get at the Hope for Wholeness site (
www.hopeforwholeness.com). Pray to God that he would help you with these thoughts. God bless and remember God is in control! P.S. As for having an open mind, it is dangerous. It is better to have it as closed as possible but not all the way closed.
