You don't need to go to the New Testament to see people seeing God and surviving.
Moses talked to God face to face. That changed with Joshua.
Deuteronomy 34:10 NET.
(10) No prophet ever again arose in Israel like Moses, who knew the LORD face to face.
Exodus 33:11 NET.
(11) The LORD would speak to Moses face to face, the way a person speaks to a friend. Then Moses would return to the camp, but his servant, Joshua son of Nun, a young man, did not leave the tent.
Exodus 24:9-11 NET.
(9) Moses and Aaron, Nadab and Abihu, and the seventy elders of Israel went up,
(10) and they saw the God of Israel. Under his feet there was something like a pavement made of sapphire, clear like the sky itself.
(11) But he did not lay a hand on the leaders of the Israelites, so they saw God, and they ate and they drank.
Exodus 33:17-23 NET.
(17) The LORD said to Moses, "I will do this thing also that you have requested, for you have found favor in my sight, and I know you by name."
(18) And Moses said, "Show me your glory."
(19) And the LORD said, "I will make all my goodness pass before your face, and I will proclaim the LORD by name before you; I will be gracious to whom I will be gracious, I will show mercy to whom I will show mercy."
(20) But he added, "You cannot see my face, for no one can see me and live."
(21) The LORD said, "Here is a place by me; you will station yourself on a rock.
(22) When my glory passes by, I will put you in a cleft in the rock and will cover you with my hand while I pass by.
(23) Then I will take away my hand, and you will see my back, but my face must not be seen."
So Moses talked to God face-to-face, but he could not see God's face.
It is quite understandable if one looks at it through the understanding of the Trinity, then we can understand that when Moses would see God face to face that we are dealing with the preincarnate Jesus, but that one either cannot see the fulness of God in the face, or possibly the Father's face and survivie.
