Oh come on Ernest, "Atheists have no "truth" that the sub-conscious mind knows is a lie" is a ridiculous statement to make, I could make equally irrelevant statements about atheists....
I have never had any doubts about the truth I know, for I have been in filled by the Holy Spirit and seen Him at work in peoples lives.
I do not dispute that there are many 'armchair' Christians who maybe have doubts, who have never had a Holy Spirit encounter and therefore cannot truly say they know the truth, because they have not me the truth.
I'm happy, even when things look bad, because I know who I believe in and He is sufficient for all things.
