No man has seen God?

In Exodus 33.20 it say to Moses "you cannot see My face, for no man can see Me and live." To some this is a contradictory statement and to others it means that Yeshua could not be God. But, this verse not only proves that Yeshua is God but also the Trinity, and in doing so doesn't come off as contradictory as some believe. God was communicating the fact that we must approach God through a perfect mediator and His way, not ours. The Tanach has many verses that say that people have seen God. Genesis 17. 1 says "Now when Abram was ninety-nine years old the LORD appeared to Abram and said unto him." In Genesis 18.1 it says "Now the LORD appeared unto him (Abram) by the oaks of Mamre." Exodus 6.2-3 says "God spoke further to Moses and said to him "I am the LORD and I appeared unto Abraham, Isaac and Jacob, as God almighty." Later in Exodus 24.9-11 it says "Then Moses went up with Aaron Nadab and Abihu and seventy elders of Israel and they saw the God of Israel." Numbers 12.6-8 says "He said, now hear my words: If there is a prophet among you I, the LORD, shall make myself known to him in a vision. I shall speak with him in a dream. Not so with My servant Moses, he is faithful in all my household; with him I speak mouth to mouth, even openly and not in dark sayings and he beholds the form of the LORD." Acts 7.2 says that "the God of glory appeared to our father Abraham." And yet, in other verses it seems that there is a contradiction. John 1.18 says that "no man has seen God at any time." John 5.37 says that "the Father who has sent me, He has borne witness of me. You have neither heard his voice at any time or seen his form." John 6.46 says " Not that any man has seen the Father, except the one who is from God; He has seen the Father." Now, it is evident from the verses in Genesis Exodus, Numbers and Acts that people saw God . Some would argue that it was a vision, dream or an angel. The problem is that the verses do not say that it was a vision, dream or an angel. They saw God and He appeared as God Almighty. There is only one solution and that is to accept what the Bible says. If Israel saw God but Yeshua says that no one has seen the Father, then they were seeing God, but not the Father. It was someone else in the God head. They were seeing the Word (John 1.1) before he became flesh(John 1.14). If God is in three persons, then Exodus 33.20 and John 1.18 is not a problem. Therefore God was seen, but not the Father. It was Yeshua before "the Word became flesh" because there is more than one person in the Godhead. Philippians 2.5-8 sums this up nicely when it says that "Have this attitude in yourselves which was also in Messiah Yeshua who, although He (Yeshua) existed in the form of God, did not regard equality with God a thing to be claimed about oneself, but emptied himself, taking on the form of a bond-servant being made in the likeness of men and being found in appearance as a man, he humbled himself by becoming obedient to the point of death, even death on a cross." He is God and only God can save man and he was the mediator that appeared to man on many ocassions. It is through him that man will one day see the face of God and live.  Bill Riley
