One thing I have noticed about the presence of God: it wets your appetite for more.

Spend a little time in God's presence and soon you won't be satisfied with just a little taste now and then. You will want more of the sweetness of His presence. More of His power. More of His glory.

That's what happened to Moses. Look at Exodus 33:18: "And Moses said, 'I beseech thee, show me thy glory.'" Moses was no longer satisfied to fellowship with God from the middle of a dense cloud. After he had experienced a little of God's glorious presence, he wanted more! He was saying, "Get this cloud out of the way, Lord! I want to see Your glory! I want to see Your face!"

Did God reject Moses' request and rebuke him for being so presumptuous? No! God will always be just as eager for your fellowship as you are for His—even more so. Remember, it was God Who set Adam in the Garden to be able to enjoy close, intimate communion with Him. It was man who put up the wall of separation between the two of them.

God will always grant you fellowship and revelation to the degree that you can handle it without being harmed.

Look at how God responded to Moses' request to see His glory:
And God said, I will make all My goodness pass before you, and I will proclaim My name, THE LORD, before you; for I will be gracious to whom I will be gracious, and will show mercy and loving-kindness on whom I will show mercy and loving-kindness.

But, He said, You cannot see My face, for no man shall see Me and live. And the Lord said, Behold, there is a place beside Me, and you shall stand upon the rock, And while My glory passes by, I will put you in a cleft of the rock and cover you with My hand until I have passed by. Then I will take away My hand and you shall see My back; but My face shall not be seen.
(Ex. 33:19-23 AMP)
That cleft in the rock is a foreshadowing of the ultimate Rock, Jesus (1 Cor. 10:4.). It is in Him that we are able to experience God's goodness and glory.
