First, thanks, David.
It seemed like what I had to add, which was at minimum a different perspective on the Christian viewpoint, was going by the boards while Theophilus on the one hand, and Gaudere and Esprix on the other, talked past each other. And Gaudere, you reason brilliantly, if a bit Jesuitically for an atheist.
One would think that you had an S.J. in your name! 
Friend of God, I may owe you an apology, and if so, you have it. You have turned anger with grace, and in that, at least, you deserve praise for following our Lord. I was quite uncharitable in my earlier posts to this thread, and should definitely mellow a bit. However, you miss the thrust of my point.
It is not for you, or me, or Esprix, or Gaudere, to decide how a fifth person should live his or her life. That is a question to be answered by that individual, guided by the Holy Spirit and God’s Word. (And, as I noted, God’s Word is not to be equated with the Bible; it is a holy record, to be sure, and I for one believe every word is there because the Holy Spirit wanted it to be. But that does not mean that it becomes the instant reference guide, with a verse tailor made for every situation: "Headache? Take two verses of Romans and call me in the morning! ;))
You have done a wonderful job of setting forth the traditional theology of salvation, complete with the substitutionary atonement. (I can just see Gaudere chuckling now.:)) However, in none of your posts do you suggest why the death and resurrection of Jesus Christ is Good News now in the present to a single web designer in Chicago, or an administrative assistant from Philadelphia in a committed relationship with a physician, or a teacher of martial arts who is training in law enforcement and who has discovered to his chagrin that sometimes God’s answer to prayer is a resounding silence. Rather, you seem set on presenting strictures on how one is supposed to live a Christian life according to your precepts. And, as I have suggested, those decisions are personal. The most you or I can do is to empathize with another’s situation, and, having done so, make suggestions in Christian charity. Esprix and I went round for round on this regarding the young man referenced earlier in this thread who is a committed Christian and member of a church which teaches that acting on his same-sex desires is sinful. While Esprix apparently was stressing the need not to repress them (and cause psychological damage), I countered that he should accept them as a part of what he is, the self God gave him, and then avoid acting on them if he believes them sinful, but use them to the greater glory of God and the furtherance of His Kingdom. You, on the other hand, would presumably suggest that he needs to go through some kind of aversive therapy to “get rid of his sinful desires.” (I am putting words in your mouth, here, I know, and I would welcome your correction of them.)
In short, where is the Gospel, the Good News, in what you have posted? Why is this a matter to bring joy to their hearts? I know from your and my perspective the idea of salvation through Jesus is something to look at in those terms – but you are not “speaking to their condition.” To Esprix, you are setting forth rules that you think God demands of him and which offends the core of his being. For Gaudere, you are another of the infinite series of people who have Found the Answer and demand that she buy into it on what is to her insufficient evidence. And up to this point, you have been showing the negatives of the human condition and not the positives of the Christian one, and sounding very legalistic on what God expects and demands.
You foolish Galatian! For the good news of Christ you have substituted the laws of men (or at least what some men believe the laws of God to be). And thus is Christ crucified in vain in your teachings.
I adjure you, by the mutual love we have in our Lord, to set forth the good news of Christ, and not the foolish teachings of men regarding Him. For He is quite able to win hearts. And that is your command, after all: Nowhere in Scripture does it say, Go thou forth in Christ’s name, and smite them about the head with thy Bible.
