Notice how the Father, God, through history often interacted with humans through humans, or angels, but almost never directly. There is a reason for this. In Revelation, it speaks of earth and sky fleeing the presence of God. This is similar to what happened at Mount Sinai. God melts everything when He directly interacts with Nature. Nature gives way to God always. Such is the nature of Nature. Of course, it cannot kill God. Even the Big Bang cannot kill God. God is utterly immortal spirit of the utmost immortality that is immune to all natural adversity. God does suffer to see His beloved suffer. It pains God. God is affected by any destruction of what He loves and who He loves. God did not even want to see Ninevah perish in Jonah’s time. God compared Ninevah city to the goard which grew up to shelter Jonah in the intense heat of the desert. God did not want the city to die, even more than Jonah did not want that gourd to die. How much more God must have suffered to allow His beloved, only-begotten son to die. But God so loved the world that He gave His only begotten Son that whosoever believes in him should not perish but have everlasting life. The Father burns up what He touches because Nature cannot sustain contact with such a holy glorious spirit. Sinai caught fire when God descended on it. Even the ark of the covenant was by its close association with God untouchable. Ever watch Indiana Jones and the Lost Ark. They captured the concept. Things closely associated with such holiness kill everything nearby because natural things are unworthy of contact with the utter holiness of the immediate presence of God. Moses had to be hidden by God in a rock cleft to protect him as God passed by. Think if God did become a human. Imagine going to school with such a being sat in class. Everyone else in class would die on the first day, in the first few seconds. Imagine if someone playing with such a being in the playground threw a ball at God. The ball would catch fire but the child throwing it would have to be put to death for throwing a ball at God. Read about God descending onto Sinai. Humans and even animals which touched the mountain while God was on it had to be put to death. Such is the nature of God’s holiness. Moses and Aaron were given special permission to go up the mountain and see God. But if for a second they had seen God’s face they would have had to die. God becoming human would be the greatest horror to ever happen. It will not happen. It would be too evil a thing to happen. The Israelites pleaded not to have to interact directly with God. They asked Moses to do that for them so they did not have to bear such terror. Moses became mediator. God was interacting so closely initially with the people that they were living in terror every day. God told Moses He sympathised with the pleas of the people. He recognised they needed Moses to mediate. Since that time God started sending prophet humans instead of directly descending in front of people. Eventually God sent the greatest possible mediator, His only-begotten Son.
