After this I looked and there before me was a great multitude that no one could count, from every nation, tribe, people and language, standing before the throne and in front of the Lamb. They were wearing white robes and were holding palm branches in their hands. And they cried out in a loud voice:
“Salvation belongs to our God,
who sits on the throne,
and to the Lamb.” All the angels were standing around the throne and around the elders and the four living creatures. They fell down on their faces before the throne and worshiped God. . .Revelation 7:9-11

The Apostle John’s vision in heaven makes it clear that everyone present will see God face-to-face. His appearance will be amazing. It is a privilege we cannot have while we are alive. Even Moses could not fully see God on earth:

Then Moses said, “Now show me your glory.” And the LORD said, “I will cause all my goodness to pass in front of you, and I will proclaim my name, the LORD, in your presence. I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion. But,” he said, “you cannot see my face, for no one may see me and live.”
Then the LORD said, “There is a place near me where you may stand on a rock. When my glory passes by, I will put you in a cleft in the rock and cover you with my hand until I have passed by. Then I will remove my hand and you will see my back; but my face must not be seen.” Exodus 33:18-23

If we were to see God fully and completely while we were alive, we would die—the image so frightening, so awesome, so overwhelming, so breath-taking it literally takes our breath away.

In heaven we will gaze in wonder at the God of this universe and bow before Jesus Himself, seeing and touching His nail scarred hands, thanking Him personally for our salvation.
