Why did Jesus need to be baptized?
Question 3014
When Jesus came to John at the Jordan to be baptised, even John was puzzled. “I need to be baptised by you, and do you come to me?” (Matthew 3:14). John’s baptism was a baptism of repentance for the forgiveness of sins (Mark 1:4). But Jesus was sinless. He had no sins to confess, no need for repentance. So why did He insist on being baptised? This question takes us to the heart of what Jesus came to do.
The Setting of Jesus’ Baptism
John the Baptist had been preparing the way for the Messiah, preaching in the wilderness of Judea and calling Israel to repentance. His message was urgent: “Repent, for the kingdom of heaven is at hand” (Matthew 3:2). Crowds came from Jerusalem and all Judea to be baptised by him in the Jordan, confessing their sins (Matthew 3:5-6).
John’s baptism was rooted in Jewish purification rituals but carried new significance. It was a public act of repentance, symbolising a turning away from sin and preparation for the coming Messiah. The prophets had spoken of a time when God would cleanse His people. Ezekiel 36:25 declared, “I will sprinkle clean water on you, and you shall be clean from all your uncleannesses.” John’s ministry was preparing Israel for this promised cleansing.
Into this setting came Jesus from Galilee. He had lived in obscurity in Nazareth for about thirty years, and now, at approximately thirty years of age (Luke 3:23), He came to begin His public ministry. His baptism would mark the transition from private life to public mission.
Jesus’ Answer: “To Fulfil All Righteousness”
When John objected, Jesus replied, “Let it be so now, for thus it is fitting for us to fulfil all righteousness” (Matthew 3:15). This phrase, “to fulfil all righteousness,” is the key to understanding Jesus’ baptism.
What does it mean? Several aspects come together here. First, Jesus was identifying with the people He came to save. Though He had no sin of His own, He was taking His place among sinful humanity. This is the principle of identification that runs throughout His ministry. As Paul would later write, “For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God” (2 Corinthians 5:21). Jesus’ baptism was a preview of His work on the cross, where He would bear the sins of others.
Second, Jesus was fulfilling the requirements of the Law. Under the Mosaic Law, priests were washed with water when they entered their ministry at age thirty (Numbers 4:3; Exodus 29:4). Jesus, who would function as our great High Priest (Hebrews 4:14-16), was ceremonially inaugurated for His priestly work. The baptism marked the beginning of His ministry of intercession and sacrifice on our behalf.
Third, Jesus was publicly affirming John’s ministry and message. By submitting to John’s baptism, Jesus endorsed John’s call to repentance and preparation for the kingdom. He was not distancing Himself from John’s work but aligning with it, showing continuity between the Old Testament prophetic ministry and His own messianic mission.
Fourth, Jesus was setting an example for His followers. Baptism would become the initiating rite for all who follow Jesus (Matthew 28:19). By being baptised Himself, Jesus sanctified the ordinance and showed that obedience to God’s commands is fitting even when we might not immediately see the necessity.
The Father’s Affirmation
What happened after Jesus’ baptism confirms its significance. As He came up from the water, “the heavens were opened to him, and he saw the Spirit of God descending like a dove and coming to rest on him; and behold, a voice from heaven said, ‘This is my beloved Son, with whom I am well pleased'” (Matthew 3:16-17).
Here we see the Trinity revealed together: the Son being baptised, the Spirit descending, and the Father speaking from heaven. This is one of the clearest Trinitarian moments in Scripture. Each Person of the Godhead is distinct, yet they work in perfect unity.
The Father’s words combine two Old Testament passages. “This is my Son” echoes Psalm 2:7, the coronation psalm declaring the Davidic king as God’s son. “With whom I am well pleased” echoes Isaiah 42:1, the first Servant Song introducing the Suffering Servant who would bring justice to the nations and ultimately bear the sins of many. In one declaration, the Father identifies Jesus as both the Davidic King and the Suffering Servant. He is the royal Messiah who will reign forever, and He is the Servant who will suffer for His people.
The Spirit’s descent “like a dove” also fulfils Isaiah’s prophecy: “Behold my servant, whom I uphold, my chosen, in whom my soul delights; I have put my Spirit upon him” (Isaiah 42:1). The Spirit’s anointing equipped Jesus for His messianic ministry. Luke emphasises this, noting that Jesus returned from the Jordan “full of the Holy Spirit” (Luke 4:1) and later began His ministry declaring, “The Spirit of the Lord is upon me, because he has anointed me” (Luke 4:18, quoting Isaiah 61:1).
The Significance for Us
Jesus’ baptism speaks powerfully to believers today. It shows us a Saviour who was willing to identify completely with those He came to save. He did not stand aloof from humanity but entered fully into our condition, though without sin. This gives us confidence to approach Him in our weakness and need, knowing He understands what it means to be human.
It also reminds us of the importance of obedience even when we do not fully understand. John did not understand why Jesus needed to be baptised. But Jesus knew it was fitting, and He submitted to the Father’s will. We are often called to obey before we understand, trusting that God’s purposes are wise and good (Proverbs 3:5-6).
Finally, Jesus’ baptism points forward to our own. When believers are baptised, we identify with Jesus in His death, burial, and resurrection (Romans 6:3-4). We publicly declare that we belong to Him and are united to Him. Just as the Father declared His pleasure in His Son at His baptism, so believers who are in Christ share in that acceptance. We are adopted into the family of God, and the Father delights in us for the sake of His beloved Son.
So, that is to say
Jesus did not need to be baptised for His own sake; He needed to be baptised for ours. By submitting to John’s baptism, He identified with sinful humanity, inaugurated His public ministry, fulfilled the Law’s requirements, and set an example for all who would follow Him. The Father’s voice and the Spirit’s descent confirmed that this was the beginning of something momentous: the mission that would take Jesus all the way to the cross, where He would accomplish salvation for all who believe.
“Do you not know that all of us who have been baptised into Christ Jesus were baptised into his death? We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life.” Romans 6:3-4
