As Moses instructs the people of Israel, before they cross over in to the Promised Land, he reminds them of what they saw when they met God at Horeb.
Moses said to them, “Remember that you saw no form when you met God, you only heard a voice. What you saw was an unbelievable sight of smoke and fire but you saw no form.” [My translation] That was on purpose!
The warning that Moses gives to the people is to be very careful to not try to make God into a likeness of anything you can see on this earth. Don’t try to bring Him down to your size! YHWH is so much greater than that!
I guess it’s normal to try and bring God down to a size that’s not so “scary,” but this is a mistake. God has revealed Himself to us that we will know how amazing and how much greater He is than us. Knowing this reminds us that He is greater than His creation, greater than we are (part of His creation), and here’s the good news; God is greater than any problem we could ever face!
Be careful to leave our cosmic creating God as big as He is. He just can’t be brought down to our size.
