(3) How are such passages as Exod. 24:10 and 33:18-23 in which it is
distinctly stated that men saw the God of Israel, to be reconciled
with such passages as John 1:18; "No man hath seen God at any time,"
and Exod. 33:20: "There shall no man see me and live"?

Answer:

_aa) Spirit can be manifested in visible form:_

in the Old Testament: Gen 16:7, 10, 13. Note here how the Angel of
the Lord is identified with Jehovah Himself, cf. vv. 10, 13. Also
Gen. 22:12--"The angel of the Lord.... not withheld from _me_."
In 18:1-16, one of the three angels clearly and definitely identifies
himself with Jehovah. Compare chapter 19, where it is seen that
only two of the angels have come to Sodom; the other has remained
behind. "Who was this one, this remaining angel? Gen.18:17, 20
answers the question; v. 22 reads: "And Abraham stood yet before

is the Angel that went before Israel. Thus was the way prepared for
the incarnation, for the Angel of the Lord in the Old Testament is
undoubtedly the second person of the Trinity. This seems evident
from Judges 13:18 compared with Isa. 9:6, in both of which passages,
