Well its very big issue these days.. Some 'christians' say its ok for an individual to be a homosexaul and God still loves them.. the truth is God loves them yes, because He is God.. He loves the sinner and hates the sin.. thats what we should be doing too. The Bible tells us man and woman are united in marriage, its not man and man or woman and woman. Sex outside of marriage is a sin.. so these two statements make it quite clear what sexual immorality is, reading 1 Cor 6:9 we see " Or do you not know not know the unrighteous will not enter the kingdom of heaven? Do not be deceived: neither the sexually immoral, nor idolators, nor adulterers, nor men who practice homosexuality." (note- they might say some versions don't say 'homosexuals' that alright tell them to check on the greek translation. it matches perfectly) if not tell them to read the book of Jude.
Oh and if they say "I was born this way" well i personally am not sure if that is right.. as far as i know that gay-gene thing is not a significant proof to justify the claim, there is also something called a 'peadophile-gene'. And if they were born that way and not a matter of choice, then how do i see Ex-Gay and Ex-Lesbians now happily married and have children, living for Christ. And even if at all its a birth thing, then also it doesn't justify.. because all of us are born as sinners.. we sin.. i tell lies, I lust, I steal, I hate, I do a lot of things that God doesn't want me to... can I be excused? ofcourse not... Sin is still sin whether we think its a choice or we were born that way. Hate the sin, love the sinner... God gave his life for us so that we will turn away from sin. God bless you!
