Should openly gay, lesbian, and transgender's be allowed to join the Church? What is your biblical views on this topic?
Note: I am not speaking about marriage.
Your question is a bit odd, because you state that the homosexual is "openly gay" but that you are not speaking about gay marriage. So are you saying they are living a promiscuous lifestyle, and are open about it? Or, are you saying that they are open about the reality of their attractions, whilst not acting upon them? Much like a person who is battling alcoholism, but resists the temptation. Admitting a weakness but not pursuing it.
If it is the latter, welcome to Christendom. If it is the former, is it not an act of proud rebellion? How does a Christian, genuine and true, rejoice in darkness, boast in it and seek validation? Has the Lord not given us the inclination towards righteousness, the grace that sets us free? What Christian proudly bares his sins, but rather are they not ashamed, seeking deliverance?
Know that a true child of God is chastised, and sanctified, and that if one were to repent, believe the Gospel, that God would set them free. They don't have to live a homosexual lifestyle, and the Lord will give them the escape as temptation presents itself.
