"Every person, therefore, on coming to the knowledge of himself, is not only urged to seek God, but is also led as by the hand to find him.
"On the other hand, it is evident that man never attains to a true self-knowledge until he have previously contemplated the face of God, and come down after such contemplation to look into himself. (1:38)"
"[M]en are never duly touched and impressed with a conviction of their insignificance, until they have contrasted themselves with the majesty of God" (1:39).
Isaiah's Vision of the Lord
Isaiah 6:1 (ESV) In the year that King Uzziah died I saw the Lord sitting upon a throne, high and lifted up; and the train of his robe filled the temple. 2 Above him stood the seraphim. Each had six wings: with two he covered his face, and with two he covered his feet, and with two he flew. 3 And one called to another and said:
“Holy, holy, holy is the Lord of hosts;
the whole earth is full of his glory!”
4 And the foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke. 5 And I said: “Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the Lord of hosts!”
Peter's Vision of the Lord
Luke 5:4 (ESV) And when he had finished speaking, he said to Simon, “Put out into the deep and let down your nets for a catch.” 5 And Simon answered, “Master, we toiled all night and took nothing! But at your word I will let down the nets.” 6 And when they had done this, they enclosed a large number of fish, and their nets were breaking. 7 They signaled to their partners in the other boat to come and help them. And they came and filled both the boats, so that they began to sink. 8 But when Simon Peter saw it, he fell down at Jesus' knees, saying, “Depart from me, for I am a sinful man, O Lord.”
Mathew 16:16 (ESV) Simon Peter replied, “You are the Christ, the Son of the living God.” 17 And Jesus answered him, “Blessed are you, Simon Bar-Jonah! For flesh and blood has not revealed this to you, but my Father who is in heaven.
John's Vision of the Lord
Revelation 1:12 (ESV) Then I turned to see the voice that was speaking to me, and on turning I saw seven golden lampstands, 13 and in the midst of the lampstands one like a son of man, clothed with a long robe and with a golden sash around his chest. 14 The hairs of his head were white, like white wool, like snow. His eyes were like a flame of fire, 15 his feet were like burnished bronze, refined in a furnace, and his voice was like the roar of many waters. 16 In his right hand he held seven stars, from his mouth came a sharp two-edged sword, and his face was like the sun shining in full strength. 17 When I saw him, I fell at his feet as though dead. But he laid his right hand on me, saying, “Fear not, I am the first and the last, 18 and the living one. I died, and behold I am alive forevermore, and I have the keys of Death and Hades.
