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

The knowledge of Jesus is the best remedy for fears: when we are better acquainted with our Lord, we part company with half our doubts-these bats and owls cannot bear the sun. Jesus in His person, work, offices, and relations, is a mine of consolation; every truth which is connected with Him is an argument against fear: when our heart shall be filled with perfect love to Him fear will be cast out, as Satan was cast down from heaven. Study then your Lord. Make it your life’s object to know Him. Seek the Holy Spirit’s illumination, and the choice privilege of fellowship, and your despondency and distress will vanish as night birds fly to hide themselves when the day breaketh. It is folly to walk in sorrow when we might constantly rejoice. We do not read that John was any more afraid after the Lord had discoursed lovingly upon His own glorious person and character. That divine enlightenment which was given to his mind, purged from it any secret mistake and misjudgment which had created excessive fear.

It is an infinite blessing to us to be utterly emptied, stripped, spoiled, and slain before the Lord. Our strength is our weakness, our life is our death, and when both are entirely gone, we begin to be strong and in very deed to live. To lie at Jesus’ feet is a right experience; to lie there as sick and wounded is better, but to lie there as dead is best of all; a man is taught in the mysteries of the kingdom, who comes to that. Moses with dim legal light needs to be told to put off his shoe from off his foot in the presence of the Lord of Hosts, but John is manifestly far in advance of him, because he lies lower, and is like a dead man before the Infinite Majesty. How blessed a death is death in Christ! How divine a thing is life in Him.  ~ C.H. Spurgeon
