Homosexuality is a sin, period. It is not some one way ticket to Hell. God sees ALL sins as equal from murder to stealing a cookie from the cookie jar. If murderers, thieves, cheats and liars are welcome into the house of God, why not gays?
There is a way to show God's love to ALL of mankind without sacrificing your core beliefs. My Church had one of the girls from out teen group come out of the closet and we didn't treat her any differently. We loved her he same and fellowshiped with her the same. She isn't suddenly turned into a leper because of her sexual orientation. But we also did not change our views on homosexuality, nor did we refrain from discussing the subject when it came up. She is a creation of God that deserves and needs love. That's it. At the end of her life, God will have the final judgement.
We are called to Love, Jesus is to Save, God is to Judge.
