A tough little question there, but here goes a shot at it.<quoted text>Welp, I've said that I would get back with you on this. Yes it is true that we will always be our parents' child (by blood as you say).. even if we (by our own choosing) wander off from their instructions and find ourselves in a place they have warned us about.
<quoted text>Let's say a person who lived the homosexual lifestyle receives Christ. They are following Christ for years... they are fine with no wish to be with the opposite sex ever again. Later on, they see an old flame and are tempted and tintillated. Through poor choices they find themselves back into homosexuality, they find scriptures condoning their lifestyle and continue to live in that situation, get married to their life-partner. You mean to tell me that - that person was never saved to begin with because they fell into temptation? Shouldn't once saved always saved keep them from falling from grace? Jesus, friend of sinners right?
You said, that he followed Christ for years, this could be a few years, a couple years, or would you say for many years? And was he a 'born again Christian'?
If it was a few years (about 3 is a few) he is still a child in Christ, and would be easily tempted yet, same with a couple of years.
If he was a mature true 'Born again Christian'(many years) he would not fall for the temptation, if the temptation did exist to him, he would shun it,(turn the other cheek), knowing that after many years of reading the Bible and talking with God, that homosexuality is called an abomination to God. Not too many sins were called 'abomination, or any descriptive words like that, they were just called SINS, so it must have been something God very much detested.
Course, we do not know that persons heart, only God does and only God would know how to handle this.
