Instead of using this analogy to stir up strife and disagreement why don't you study 1 Cor 5 and see that Paul left it up to God to deal with a professing Christian in open sin. Perhaps you are better than Paul to judge in Gods place on the matter. One of the five "I wills" of Lucifer.But everyone's message here is no different than the man who is cheating on his wife. The only difference is that they are cheating on God instead. They believe they will forever cheat or sin on God even though they really do not mean to do so. Such a claim is neither Biblical nor does it line up with any sense of common basic morality that we know about.
