David Wilkerson identifies four fears
“Awake, awake, put on strength, O arm of the Lord; awake, as in the ancient days, in the generations of old. Art thou not it that hath cut Rahab, and wounded the dragon?… Awake, awake, stand up, O Jerusalem, which has drunk at the hand of the Lord the cup of his fury; thou hast drunken the dregs of the cup of trembling, and wrung them out….
“Thus saith thy Lord the Lord, and thy God that pleadeth the cause of his people, Behold, I have taken out of thine hand the cup of trembling, even the dregs of the cup of my fury; thou shalt no more drink it again” (Isaiah 51:9, 17, 22, my italics).
Isaiah says there are four great fears mixed into this intoxicating cup of fury. In this powerful prophecy, the prophet tells us God has put into the hands of all nations a “cup of trembling.” This cup is of the Lord’s doing, and it is filled with the wine of fear, hopelessness and perplexity.
