Why is the baptism of Jesus important?

Christ's baptism holds deep theological significance as it represents His identification with humanity and the fulfillment of God's redemptive plan. In Matthew 3:15, Jesus states that it is to 'fulfill all righteousness.' His baptism serves as a symbolic act demonstrating His willingness to bear the sins of His people, though He Himself was without sin. By undergoing baptism, He validates the sacrament and sets a precedent for believers. Furthermore, it highlights the unity of the Father, Son, and Holy Spirit at that moment, confirming Jesus as the Messiah who would fulfill the Law perfectly on behalf of His people.
