The entry of triumph of the Son of God into Jerusalem marked the beginning of the end. The end of the old order. The end of the old Jerusalem. The end of the old administrations of the covenant. The end of the old temple. The end of shadows and types.
The New Jerusalem had come to Jerusalem. The New High Priest had come to replace all old priestly types. The True Sacrifice had come, the Lamb of God, to replace all shadows in lambs and bulls and goats. The Blood of the Son of Man had come and would be shed for His people and the Atonement so longed for had come to replace the atonements that only pointed to something greater. The new Man had come, replacing the old humanity, the New Adam for the old, first, fallen Adam. The new Temple had come and when the old temple destroyed it, God rebuilt it in only three days, and then destroyed the old.
The celebration of Palm Sunday is a celebration of victory – victory over death through death. Victory over sin by One who had no sin taking all of our sin upon Himself. Victory over the curses of God by becoming the curse of God and hanging on a Tree. Victory from the Tree of God’s curse to the Tree of Life – tearing the veil in two and lifting the prohibition – now all men could come and partake – but only through the cross, only covered in the blood, only washed in the waters of His Spirit-baptism.
Children would sing. Infants would declare the Good News. Demons would tremble and religious types would try to keep those little ones away. But Jesus would declare “let the children come to me” and children, you are all welcome – welcome to come to Jesus with us – to confess Him and worship with us. We are told to have faith like you have. We are told to come with you and worship. “Out of the mouth of babes and nursing infants, you have ordained strength because of your enemies, that You may silence the enemy and the avenger.” With the coming of Jesus – everything is turned on its head. The world is turned upside down.
