Mark 1:9-11 NIV
[9] “At that time Jesus came from Nazareth in Galilee and was baptized by John in the Jordan. [10] Just as Jesus was coming up out of the water, he saw heaven being torn open and the Spirit descending on him like a dove. [11] And a voice came from heaven: “You are my Son, whom I love; with you I am well pleased.”

How fitting that the Father, whose commission Jesus, His Servant, had come to fulfil, should authenticate Him at the start of His public ministry! How better than to own and affirm Him as His Son! Jesus, the man, was not just any man… not even a special man chosen for the job. He was God’s own Son, very God Himself, born in human form, to carry out a mission so risky and so sacred that only one person could pull it off.

This Servant needed the Father’s affirmation to secure Him and the Holy Spirit’s anointing to empower Him. Following the act of baptism, immersion in the waters of “mikvah”, for Him the Jordan River, He was set apart for His work to which He dedicated Himself with unwavering faithfulness.

According to Google,

“Jesus’ baptism, as recorded in the Gospels, was a significant event with multiple layers of meaning. It marked the beginning of Jesus’ public ministry, symbolized his identification with humanity and their need for salvation, and demonstrated his submission to the Father. Furthermore, it was a pivotal moment where the Holy Spirit descended upon him, and the Father’s voice affirmed Jesus as his beloved Son.”

Like the action of ordinary humans when they submitted to the ceremonial washing of the “mikvah”, Jesus also drew a line in the sand. His action was much more than obedience to a ritual demanded by the religious culture of His people. It was a declaration of intent, His dedication to the greatest purpose of the Father symbolically expressed in the act…the washing away of sin, not by water but by His own blood.

Like the believers who would follow Him, His baptism would forever cut Him off from any other pursuit than to do the will of the Father. His role as the Ebed Yahweh was cemented in that act.

Matthew 3:13-15 NIV
[13] Then Jesus came from Galilee to the Jordan to be baptized by John. [14] But John tried to deter him, saying, “I need to be baptized by you, and do you come to me?” [15] Jesus replied, “Let it be so now; it is proper for us to do this to fulfill all righteousness.” Then John consented.”

Jesus was secured in the Father’s love and affirmation, after thirty years of living in a Galilean village in obscurity, by “the Father’s blessing”. He would have been insecure and adrift without the verbal affirmation from the Father, of His belongingness and approval. Armed with the Father’s words ringing in His soul, Jesus could step out into a hostile world with the assurance that He was beloved and supported by the greatest power on earth and empowered by the Holy Spirit Himself to carry out the Father’s will.

So, from that moment, Jesus set His face, ultimately, towards Jerusalem, the centre of Israel and the place where all the prophetic visions of the Messiah would come together to fulfill God’s great plan of salvation. Though His earthly ministry would range across Israel and beyond, beginning at the Jordan River, and crisscrossing the territory of His people, it would culminate, from the heart of God to the heart of His nation, in the mighty return of His Spirit in Jerusalem, to indwell His people and to finish what He started.
