In Col 1:15, 1Ti 1:17, 1Ti 6:16, and Heb 11:27, we read that God is invisible. Interestingly, the word for the Lord's THRONE in the OT has the idea of causing a crease in the fabric so as to create an area for manifestation. We read that the (lower) heavens are spread out as a garment for this very purpose.I think those who saw angels in the Bible more than merely passed out, and will take it one step bolder to say that it seems that even seeing an angel caused death in those who were accustomed to having angelic ministry about them. They had to be resurrected when this happened. All these men were of great faith. Paul said whether in the body or out of the body he knew not. For example, Eze 1:28 provides the same word as the word 'perish' (fell), while the next verse provides 'stand', elsewhere rendered, '(to) raise up'.It is written that no man has seen God at any time (as to His essence), yet we read the Lord Himself explaining to Thomas in Joh 14:7, "If ye had known me, YE SHOULD HAVE KNOWN my Father also: and from HENCEFORTH YE KNOW Him (The Father), and have SEEN Him (The Father)."SEEN=to see with the mind, to perceive, know (as the Christ has clarified in the above verse)Where is Christ at the time present? See Col. 3:3, Christ is hid in God, vv. 4, when He manifest...so Christ is not now manifest, He is hid in God.
