Matthew indicates that this baptism is a collaborative effort: “Let it be so now; for it is proper for us in this way to fulfill all righteousness” (3:15). John must concede to baptize Jesus; Jesus must seek the baptism of John. Together, their obedience to God’s plans is a step on the path of righteousness.

Second is the aim of “fulfill[ing] all righteousness.” What might this mean?  The Greek term is incredibly difficult to define, and even more difficult to comprehend theologically. The term can encapsulate complex notions of justice, uprightness, correctness, innocence, and redemption.

Thus, “to fulfill all righteousness” likely means acting in obedience to God in a way that coordinates internal dispositions and external action. Jesus’ first steps in public ministry are a combination of a compliant spirit and a powerful, public display of his obedience to God’s call.

“…with whom I am well pleased.”
That Jesus’ baptism is essential and a step of righteousness is confirmed by the divine voice.  God’s approval is unequivocal. Jesus is reaffirmed as God’s child as he begins his journey to the cross. Moreover, God’s love for Jesus is reaffirmed as well. Though Jesus’ life will be characterized by temptation and suffering, God’s love is no less real. God’s approval of Jesus is multifold. He and John together have acted in obedience to God at this moment, and now Jesus will certainly not divert from the straight path laid before him.
