The Son of David Ascends His Throne and Reigns in Love from His Cross The Son of David comes in gentle humility, “sitting on a donkey’s colt,” yet as the King of Israel “in the name of the Lord” (John 12:13–15). He comes to be lifted up in glory on the cross in order to cast out “the ruler of this world” and draw all people to Himself (John 12:23–32). The Church is thus called to “rejoice greatly,” because her King comes with salvation, and “he shall speak peace to the nations” (Zech. 9:9–10). As He is anointed “beforehand for burial” (Mark 14:8), He also ascends His royal throne as “the King of the Jews” by way of His Passion (Mark 15:2, 17–19, 26). He goes “as it is written of him,” wherefore “you will see the Son of Man seated at the right hand of Power” (Mark 14:21, 62). For the glory of God is love, which crescendos in the humble obedience and voluntary self-sacrifice of the Son of God for the salvation of sinners. So, God the Father has “highly exalted him and bestowed on him the name that is above every name” (Phil. 2:9), that He might reign over us in love with the forgiveness of His cross.
