Introduction:
The baptism of Jesus is a significant event in the New Testament, marking the beginning of His public ministry. This event is recorded in the Synoptic Gospels: Matthew, Mark, and Luke, with a brief mention in John. It is a moment of divine revelation and affirmation of Jesus' identity as the Son of God.

Biblical Account:
In the Gospel of Matthew, the account of Jesus' baptism is detailed in Matthew 3:13-17. Jesus travels from Galilee to the Jordan River to be baptized by John the Baptist. Initially, John hesitates, recognizing Jesus' sinlessness and expressing that he himself needs to be baptized by Jesus. However, Jesus insists, saying, "Let it be so now; it is proper for us to do this to fulfill all righteousness" (Matthew 3:15). Upon being baptized, Jesus emerges from the water, and the heavens open. The Spirit of God descends like a dove and rests on Him, and a voice from heaven declares, "This is My beloved Son, in whom I am well pleased" (Matthew 3:17).

Mark's Gospel provides a succinct account in Mark 1:9-11, emphasizing the divine voice and the descent of the Spirit. Luke 3:21-22 also records the event, noting that Jesus was praying as the heavens opened.

The Gospel of John does not describe the baptism directly but refers to it through the testimony of John the Baptist, who saw the Spirit descend and remain on Jesus, affirming Him as the "Lamb of God" (John 1:29-34).

Theological Significance:
Jesus' baptism holds profound theological implications. It signifies the inauguration of His public ministry and His identification with humanity. Though sinless, Jesus submits to baptism, symbolizing His willingness to take on the sins of the world. This act of humility and obedience sets a precedent for Christian baptism, representing repentance and the washing away of sins.

The presence of the Trinity is evident in this event: the Father's voice, the Son's obedience, and the Spirit's descent. This Trinitarian manifestation underscores the divine nature and mission of Jesus.

Fulfillment of Righteousness:
Jesus' statement about fulfilling all righteousness highlights His role in fulfilling the Law and the Prophets. His baptism is an act of obedience to God's redemptive plan, aligning with the prophetic tradition and foreshadowing His sacrificial death and resurrection.

John the Baptist's Role:
John the Baptist serves as the forerunner to the Messiah, preparing the way for Jesus. His baptism of repentance sets the stage for the coming of the Kingdom of God. John's recognition of Jesus as the "Lamb of God" points to Jesus' ultimate purpose as the Savior.

Symbolism of the Dove:
The descent of the Holy Spirit in the form of a dove symbolizes peace, purity, and the anointing of Jesus for His messianic mission. It marks Jesus as the chosen one, empowered by the Spirit to fulfill His divine calling.

Divine Affirmation:
The voice from heaven serves as a divine affirmation of Jesus' identity and mission. The declaration, "This is My beloved Son," echoes Old Testament messianic prophecies and confirms Jesus as the Son of God, beloved and pleasing to the Father.

Conclusion:
The baptism of Jesus is a pivotal moment in the Gospels, rich with theological meaning and significance. It marks the beginning of His ministry, affirms His identity, and sets the stage for His redemptive work.
