We seem to be circling toward a mutual understanding. Yes, we’re to preach (although I prefer conversations to monologues), but we should preach the gospel, preach scripture, and resist the temptation to embellish it with our own opinions, which is what the notion of homosexuality (the inner compulsion, not the outer behavior) being a conscious choice is. It’s an opinion. There’s decades worth of research tying environmental (or traumatic) factors to homosexual inclinations; and there’s not a single scripture that either affirms or contradicts that conclusion.
It’s simply a false choice to say that the homosexual compulsion has to either be inborn or else a conscious choice. There’s nothing God-denying in claiming the third, best evidenced alternative, that the compulsion is something deeply rooted that comes about based on things someone experiences very early in life. Temptation can lead to sin, but temptation itself is not the sin, and I don’t have God’s eyes to peer into someone’s heart and tell them that they chose to be tempted.
As I said before, when a person recognizes that compulsion, THEN they have to make a choice as to what to do about it; either choosing to sin by embracing and affirming the compulsion, or choosing to combat it. There’s simply no need for Christians to adopt a posture that needlessly puts up a wall between us and someone we’d like to bring to Christ by starting off by our telling them that they chose to feel that way in the first place. For one thing, that mis-prioritizes the situation, giving the path behind more significance than the path ahead. And making such pronouncements publicly will almost certainly prevent such a Christian from being approached by anyone who might be looking for some Christian compassion as the first step toward making a change. Sadly, it might dissuade them from approaching ANY Christian.
