Lots of problems with that link. The closest biblical passage resonating with it is in Acts 17;27
"God intended that they would seek Him and perhaps reach out for Him and find Him, though He is not far from each one of us. 28
‘For in Him we live and move and have our being.’ As some of your own poets have said, ‘- We are His offspring.’ 29Therefore, being offspring of God, we should not think that the Divine Being is like gold or silver or stone, an image formed by man’s skill and imagination.…"
Yet it is clear from the above that God and mankind are separate and separated, conceptually, physically and spiritually. God does hide himself from the unbeliever. That is why the unbeliever cannot form any coherent argument against God, because he is devoid of power, ability and even sanity in some cases, e.g. Nietzsche. To know God, man must reach out for God and find him. If he sits around waiting for a Damascene vision, it may never come where the sinner is content to wallow in his pride and arrogance but wthout acknowledging divinity. A misguided person may be corrected and reproved by God, but a lazy indolent person who thinks he knows it all should not assume it.
