In the year that king Uzziah died, I saw also the Lord sitting upon a throne, high and lifted up, and his train filled the temple.
Above it stood the seraphim; each one had six wings; with twain he covered his face, and with twain he covered his feet, and with twain he did fly.
And one cried unto another, and said: Holy, holy, holy, is the Lord of Hosts; the whole earth is full of his glory.
And the posts of the door moved at the voice of him that cried, and the house was filled with smoke.
Then said I: Wo is unto me! for I am undone; because I am a man of unclean lips; and I dwell in the midst of a people of unclean lips; for mine eyes have seen the King, the Lord of Hosts.
I can’t say that I’ve seen the Lord directly, and I don’t know anyone personally who has. I do know that I’ve found the thought terrifying at times. Like Isaiah, we’re all unclean in some way, and so the thought of coming into the presence of a being who is so Holy and beyond our comprehension – let alone the actual experience – is unsettling. At least for me; some people seem far more relaxed about the prospect. I’m not sure if that’s proper spiritual confidence (D&C 121:45) or complacency; I guess it varies. I suspect that when one realises ones own state and who God is, then unless one has received the confidence spoken of in D&C 121:45, some degree of consternation like Isaiah’s is the only proper response. This is particularly the case when we realise that one day, all of us will come into the presence of God to be judged.
Fortunately the Lord is merciful, and able to cleanse us:
Then flew one of the seraphim unto me, having a live coal in his hand, which he had taken with the tongs from off the altar;
And he laid it upon my mouth, and said: Lo, this has touched thy lips; and thine iniquity is taken away, and thy sin purged.
