"A hand reaches down from heaven holding a cup, filled to the very brim, and as the holy Savior looks into that cup, He becomes pale with horror...His eyes stare in wild despair as the great drops of blood ooze from His unbroken skin, and finally He cries out in the agony of His soul, 'My Father, if it be possible, let this cup pass from me.' But the cup remains, and again the cry, and a third time He cries, 'Father, if it be possible, let this cup pass from me.'
WHAT WAS IN THE CUP?
"What in all the world could make the Son of God shrink and cry in agony? What, oh, what was in this cup to make Him cry for deliverance? He who shrank not from the jeering mob, He who feared not those who would slay Him, He who later went without murmuring to the Cross, to die without complaint, what is this awful thing which makes Him cringe now, and cry out to the Father?" -The Tabernacle
by DeHaan, page 153.
What was in the cup? The wrath of God poured out on sin - your sin and my sin, the sin of the world.
"Death and the curse were in our cup:
O Christ, ’twas full for Thee;
But Thou hast drained the last dark drop,
’Tis empty now for me." -O Christ, What Burdens Bowed Thy HeadJeremiah 25:15
"For thus the LORD, the God of Israel, says to me, 'Take this cup of the wine of wrath from My hand and cause all the nations to whom I send you to drink it.'"
