Matthew tells us that Jesus was baptised in the River Jordan by John to “carry out all that God requires”. A better translation of this might be to “fulfil all justice”, a justice that comes from the heart of God. It is clear from the outset of Jesus’ ministry that he is on the side of the weak, the helpless, the people at the margins of his society. Fulfilling all justice, then, is doing things the way God wants them to be done.
