We were created for and by God In His image. To do His will. To have fellowship with Him. Yes, life on this earth will end. But to live in sin as a homosexual will bring Eternal Death. For this kind will not inherit the Kingdom of God. For in Heaven there will be no sin.
Who we believe in will determine our Eternal Life. For you cannot serve God and Satan. You will serve one or the other. One brings Eternal Life in Paradise, and one brings Eternal damnation into hell.
Hate the sin, love the sinner.
