Epiphany 1
There could be no more proper or fitting way for him and John (“for us”) to inaugurate his public redeeming work. Nothing could be more becoming than that Jesus ask to be baptized and that John consent to baptize him. For in doing so, they were about to “fulfill all righteousness.”
Here is the point where many go wrong. They take “to fulfill all righteousness” to mean “to fulfill the whole law of God for us, to meet all its requirements in our stead.” But this cannot be meant—for two reasons. First, in that case Jesus would have to speak of what was necessary, not what was proper. He was under obligation to fulfill all the demands of the law for us who were under the law, that is, under its condemnation. (Galatians 4:4, 5) That was a “must,” something absolutely necessary.
Secondly, it cannot be shown that baptism was a legal requirement. Baptism as a sacrament was unknown until this time. Yes, there were rites of purification prescribed by the Mosaic law, but none of these was a sacrament, as baptism is. The Jews indeed expected their Messiah to bring purification from sin. (See especially Zechariah 13:1.) Accordingly, that the expected Redeemer would administer a rite that cleansed from sin and guilt was in line with such expectations. Because John came with a “baptism for the forgiveness of sins,” he caused them to wonder whether he might not be the Messiah (Christ). This thought lay behind their question: “Why then do you baptize if you are not the Christ, nor Elijah, nor the Prophet?” (John 1:24).
We must forget about the idea of Jesus fulfilling some legal requirement by permitting himself to be baptized. Here we are in the field of the gospel. Jesus was beginning his earthly mission of being the divine substitute for sinners. John could not have a part in the redeeming work itself, the work of “fulfilling all righteousness,” that is, of carrying out fully the Father’s redeeming will for the slaves of sin. But John could and did have a part in ushering in Jesus’ work as the Christ. Both together, John by baptizing one who was sinless and divine, and Jesus by submitting to a baptism he did not need, took the divinely proper way of telling sinful men: Here Jesus steps to your side, takes up your cause, and sees it through to the bitter and victorious end!
