“The next day a great multitude that had come to the feast, when they heard that Jesus was coming to Jerusalem, took branches of palm trees and went out to meet Him, and cried out: ‘Hosanna! Blessed is He who comes in the name of the LORD!’ The King of Israel!’ Then Jesus, when He had found a young donkey, sat on it; as it is written: ‘Fear not, daughter of Zion; behold, your King is coming, sitting on a donkey’s colt’ ” (John 12:12-15).
“Here Christ is not only declared to be “king,” but He accepts the public lauding of Himself as king, despite Pharisaic rebukes (Matt. 21:15-16), for it was in fulfillment of prophecy (Zech. 9:9).
“The anticipation of this enthronement is clearly evident in His post-resurrection, pre-ascension Great Commission.16 In Matthew 28: 18-20, we read a statement much in contrast to His earlier reservation and humility. No longer do we hear the familiar, “I can do nothing of Myself” (John 5:19, 30; 8:28; 12:49; 14:10). Rather, we hear a resoundingly powerful: ”All authority has been given Me in heaven and on earth.” A mighty transformation has taken place in the ministry of Christ as a direct result of His resurrection. Satan has been conquered;1Christ has overcome the world to be “declared the Son of God with power” (Rom. 1:3, 4). The Great Commission is truly a postmillennial commission.
“He delivers to His few followers the obligation and plan for universal conquest: “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit, teaching them to observe all that I commanded you” (vv. 19-20). The command of the resurrected Christ who possesses “all authority” is for His followers to bring all nations’ as nations to conversion and baptism. The word ethne is employed rather than basileia to show that His concern is not for earthly political power. The word anthropos is passed by in demonstration of His concern for the transformation of all of culture, rather than just individuals. This is precisely the expectation of so many of the Old Testament prophecies, which foresaw all nations flowing to Mount Zion (e.g., Isa. 2: 1-4; Mic. 4:1-4), and which anticipated “no more shall any man teach his neighbor, ‘Know the Lord, for they shall all know the Lord'” (Jer 31:34; cf. Isa. 11:9).
