Premise 1: There must be only one absolute truth which provides reason for -- i.e. it explains -- everything (tautological).
Yes, but. When you consider the size of the universe (assuming that existence is more than a mere mental aberration of some kind), and that the whole thing from max to min fits together and works quite well, and that it all works by cause and effect, who is there that might have any clue as to what the REAL truth is?
Premise 2: There must be only one absolutely correct reason/explanation of that truth (axiom, i.e. absolute truth = absolute truth).
Usually explanations of things, if comprehensive, tend to be larger than the things themselves. This makes the truth to be its own explanation.
Premise 3: There are two or more people in this post who state belief in the Christian god (let's assume Christian god = absolute truth, for the sake of argument), but for different reasons/explanations.
Do you mean your post here? Or did you mean "thread" but only said "post?"
Conclusion 1: Therefore, the reasons/explanations provided by at least one (possibly all) of these posters is incorrect.
All. But even if it were correct, it would be incomplete.
Conclusion 2: Therefore, at least one (possibly all) of these posters believes in something that is not absolute truth/Christian god.
Was Jesus blonde, brunette, or redhead? When the Holy Spirit talks to the heart of a person and works salvation in him, the color of Jesus' hair doesn't matter, and probably isn't revealed. The Revelation in the Bible says that His hair is "white like wool." Yet, it may not have been that color when He walked the earth.
Salvation of certain people among the masses of mankind is a thing worked by the TRUTH, not a thing worked by mankind's knowing of the whole TRUTH, which is impossible... at least in this life.
