When I was teaching at the divinity school, I took a group of students to the slum area; a sight-seeing tour to be sure. I asked one student to go and sit beside a drunk in the street, put his arm on his shoulder and tell him that he loved him and so did Jesus.
The student replied, "I can't do that."
My response, "This is the gospel. Perhaps you have chosen the wrong field."
This is the gospel. We must love all peoples where they are, and in whatever state they are in. If we lose sight of this then we are as sounding brass and tinkling cymbals, preaching to the elite, the clean and neglecting the very things our Lord so graciously did throughtout His ministry, and afterall, is He not the Word?
I am not certain about the genetic beginnings of homosexuality. The one study was done by a homosexual who had an agenda, and he alone said science proves that homosexuality is genetic. The medical profession, as a whole, is not so certain on that point.
Aside from that, we know that the Holy Spirit is the author of change, and in His work, all things are possible,,,,even genetic conversion. In the interim, we must treat people where they are. We must love them in Christ. We must treat them decently. I think this is what Post-It is trying to say. Despite the sin, we love them. Because of the sin, we love them more.
In all things, let us lift the Saviour high, and bow ourselves before Him, in love and determination to what is right in His eyes.
Cheers, and God bless,
Jim
