Matthew 18:15 Moreover if thy brother shall trespass against thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother.
Matthew 18:16 But if he will not hear thee, then take with thee one or two more, that in the mouth of two or three witnesses every word may be established.
Matthew 18:17 And if he shall neglect to hear them, tell it unto the church: but if he neglect to hear the church, let him be unto thee as an heathen man and a publican.
1. Jesus is very clear, if a Christian is living a sinful lifestyle you are REQUIRED BY GOD'S LAW to confront them and let them know they are sinning. If they do not listen to you, bring to a group of Christians and then the Church, if the person rejects everyone's helping hand so that they can continue in sin Jesus tells us to not regard that person as a Christian.
2. There is a difference between sinning as a human which we all do, and knowingly breaking God's law daily. That was the fall of lucifer along with the fallen angels, they knowingly and willingly openly rebelled against God to satisfy their own selfish desires. Not saying Homosexuals will be damned to the Lake of Fire like satan since we are still in the flesh, but they are not Christians and should not be treated as Christians.
3. It is perfectly fine if people choose to go against God's law and live for this life instead of the next, everyone has free will. That is what the Millennium is for, to teach and give the people unable to be Christians now a chance. Do not kill homosexuals or mock them, just know they are living in sin, but of course show Godly love towards them like you would everyone even your enemy as Jesus commanded us too.
4. If we can be honest, the only reason why homosexual behavior is as tolerated as it is by the Christian community is because the world has made most of you numb to it. Since we talking about family members falling to sinful lifestyle and us being compassionate, if your son was a murderer, coming every day to visit you telling of today's murder would you be so welcoming and compassionate to embrace them as a father/mother and a Christian? Not even doing it once and repenting and serving jail time, then coming home a new person. But just daily killing people, and not caring it is wrong. "They are Christians, they just need time to work out their demons". Lets be real.
