Hmm- that is an interesting way of looking at it and may well be totally valid in some cases- though I agree with heralde in that it's not necessarily true in all cases. However, "homosexuality" is the technical term and it is the term used in The Bible, along with sexual immorality, which covers a wider range. God makes it clear in The Bible that both the physical act of men lying with men and women lying with women in a sexual manner is wrong. But He also condemns the attraction and desires that go with it. It all goes back to lust really. Whether it's lust for a homosexual relationship or lust for a premarital heterosexual relationship, it's still wrong.
Perhaps the distinction some pastors might use between "homosexuality" and "gay" and/or "LGBT" is not so much just on the physical aspect of it- though that is certainly covered as well. When people refer to the "gay community" and/or "LGBT community" then it seems they have identified their entire life solely by that characteristic. I mean, heterosexuals don't refer to ourselves as the "heterosexual community".
I suppose it's the same reason people don't generally like to refer to themselves as the "lascivious community" or the "liar community" or the "thieves community" or the "hypocrites community" or the "pride community", etc. People don't want to identify themselves by one sinful act because they don't want to sound like a bad person overall.
Of course, the ironic thing is that we all comprise such communities because we have all sinned and done wrong in different ways.
I'm fully aware that a lot of people struggle with homosexual tendencies, but I don't think that makes them a separate species, if you will. Whether people are honest enough to admit or not remains to be seen, but there are even Christians who struggle with it- because we all struggle with all sins to some degree or another. Some hold greater temptations to some than others. As 1 Timothy 5:24 says, "The sins of some men are obvious, going ahead of them to judgment."
But no matter what your sin struggle is, Jesus Christ died on the cross to pay for every single one of them ever committed. All the sins anyone's ever done, is ever doing and will ever do. And He rose again to prove He's God and to give us eternal hope in conquering the grave and enjoying the free eternal life that He offers.
The reason why Christians repeat this awesome, incredibly Good News ad nauseum is because Jesus told us to, for starters. (Matthew 28:18-20) Also because God is not willing that any should perish but that all should come to repentance. (1 Peter 3:9) The reason is not to offend anyone or condemn anyone. John 3:17 says that even Jesus didn't come to do that. Rather, He came to save the world! (John 3:16) He loves us, He died for us, He rose again and He wants us to know Him as Savior. That's The Gospel. "If you confess with your mouth, 'Jesus is Lord' and believe in your heart that God raised Him from the dead, you will be saved." (Romans 10:9)
Whether gays, LGBTs, homosexuals or however folks want to identify themselves have their version of marriage is besides the point in that regard. The point is that God loves all people and desires all people to come to a knowledge of Him. When the options are either come to know Christ and spend eternity with Him in Heaven or reject Him and spend an eternity in the lake of fire, I think it bears repeating ad nauseum in the hope that the Holy Spirit will penetrate someone's soul and shower them with the love and eternal hope found in Jesus alone.
Now if people have already made up their minds about Jesus, then that's fine. I can't do anything to twist anyone's arm and I don't want to. That's not my position. I can pray for folks and trust God to work, but He's the One who does the saving. I just want everyone to truly consider what Jesus says regarding eternity and if they've really done that and made their decision, then there's nothing more to be said- other than a hearty "Congratulations and welcome to the kingdom of God" for those who choose Christ as Savior and a desperate cajoling and pleading for those who choose to deny Him- although Luke 10 also counsels that there may be a time when you have to shake the dust off your feet from the town that refuses to listen.
But it's a matter of love for the world and wanting to give everyone a chance to know Jesus and have salvation. It's not about lifting myself up or being superior or any of that junk- because I'm not. I'm nothing- without Christ. (John 15:5) It's about showing Jesus' love to everyone and sharing the Good News of salvation that He offers to all. So I hope everyone understands that when I say such things and when any other Christian says this, it's said out of obedience to Jesus and a heart of love.
And it's a choice everyone has to make for themselves- and you're still gonna be loved whatever choice you make.
