Being homosexual in and of itself is not a sin, it is the act of homosexuality. I view homosexuality as being very similar to a porn or sex addiction. The difference? A homosexual is attracted to the same sex. Both things are sins, encouraging marriages between same sexes is like encouraging someone to look at porn or have promiscuous sex, bad idea.
The bible DOES make it clear that it is a sin no matter how you look at it, or how others like to construe verses and take things out of context. Sin is sin.
I think I see what you are saying but you cannot be a homosexual if you are not practicing the sin..even if it's in the heart and mind..and not the body..
just like an adulterer is an adulterer because of the things he thinks about and does.
(remember Jesus said if you look upon a woman with lust in your heart you have commited adultery with her)
We practice sin because we choose to...for whatever reason and often times we are in bondage and Christ came to free us from that..
All of us suffer from some form of difficulty getting out from under bondage even though we have the Holy Spirit to give us that power...and often it's in our own flesh desires we can find that answer..
Many sins are so repulsive to us that we struggle with that of course we will not want to deal with it..
but often times, mostly sexual sin is so pleasurable in that person's flesh and mind they will justify their lifestyle
so that they won't have to A. feel convicted and B. give it up and over to Jesus.
As christians we DO have not just the right to be our brother's keeper but the command..
Luke 17:3, 2 Thess 3:15, Gal 6:1,2 Tim 4:2, 1 Tim 5:20, Titus 3:10-11 (which often should be practiced even in these forums
, Heb 4:11....and more all tell us to warn, exhort, reprove, correct and try to help turn our "brother" to the right instead of the left..
the key is to do it in love and not condemnation.. even tough love is love..
The book of timothy is clear when someone in the "Church" continues in a sin that he has been warned about, corrected and reproved etc..and still will not turn we are to treat them as a tax collector or pagan..
The reason for this just as in 2 Corinthians 7 is because it will hopefully produce godly sorrow which leads to repentance..
and to keep them from spreading that sin in the church..
so it's all done in love for that person who is lost or behaving lost..and for others in the body.
Too often we skip the parts of the bible that seem harsh because we lean on our own understanding but we must remember This is a manual for how to live an abundant life here and for eternity ...through love...for others above ourselves..and loving God with all our heart mind body and soul...and it features the WORD Jesus.. our rock and redeemer.
Some people come here for real help, real needs.. ,some come to troll and some ask for help but really just want to justify their sin practice lifestyles..
So Scripture has a "what to do" for the latter two..
1 Corinthians 5:11
Amplified Bible (AMP)
11 But now I write to you not to associate with anyone who bears the name of [Christian] brother if he is known to be guilty of immorality or greed, or is an idolater [whose soul is devoted to any object that usurps the place of God], or is a person with a foul tongue [railing, abusing, reviling, slandering], or is a drunkard or a swindler or a robber. [No] you must not so much as eat with such a person.
