And when I saw Him, I fell at His feet as dead. And He laid His right hand upon me, saying unto me, Fear not; I am the first and the last: I am He that liveth, and was dead; and behold, I am alive for evermore, Amen. – Revelation 1:17,18

In order to complete the cure of His servant our Lord went on to give him fuller instruction in that very matter which had overpowered him. Sometimes like cures like. If in a certain sense it is true of divine revelations, that “shallow draughts intoxicate the brain,” it is assuredly true that “drinking largely sobers us again.” If a glimpse of Christ makes holy men to faint, a clearer sight of Him will set them on their feet again. Our Lord went on to instruct John in the glory of His person and power, that his fears might be removed. And truly, brethren, John was in a right state for such celestial instruction; he who is lowly is ready to learn mysteries. He was like wax ready for the seal; or as paper cleansed of all other writing. Because we think we know, we know not; but the death of the pride of knowledge is the birth of true understanding. The Lord loves best for pupils those who lie lowest before Him. “The meek will He guide in judgment, the meek will He teach His way.” “With the lowly is wisdom.” Where Jesus is the teacher, and instructs the heart in the things concerning Himself, the soul is made to inherit substance, and its treasures are filled. Blessed are the men who are taught by Him who is the wisdom of God, even though while they watch at the posts of His doors they lie as dead men; they are blessed, for they shall find life, and obtain favor of the Lord. ~ C.H. Spurgeon
