But Jesus answering said unto him, "Suffer it now; for thus it becometh us to fulfil all righteousness" (R.V.). Though about to enter on His Messianic work, He has not yet taken its burden on Him; accordingly He comes, not as Messiah, but in the simplest and most unassuming way; content still, as He has been all along till now, to be reckoned simply as of Israel. This is what we take to be the force of the plural pronoun "us."
On the other hand, it should be remembered that Jesus must have recognised in the summons to the Jordan a call to commence His work as Messiah. He would certainly have heard from His mother of the prophetic words which had been spoken concerning His cousin and Himself; and would, therefore, as soon as He heard of the mission of John, know well what it meant--He could not but know that John was preparing the way before Him, and therefore that His time was close at hand. Of this, too, we have an indication in His answer to the expostulation of John. "Suffer it now," He says; as if to say, I am as yet only one of Israel; My time is at hand, when I must take the position to which I am called, but meantime I come as the rest come: "Suffer it _now_; for thus it becometh us to fulfil all righteousness."
While then Jesus came simply in obedience to the will of God, He must have come with a very heavy burden. His study of the Scriptures must have made Him painfully familiar with the dark prospects before Him. Well did He know that the path of the Messiah must be one of suffering, that He must be despised and rejected, that He must be wounded for the people's transgressions and bruised for their iniquity; that, in a word, He must be the suffering Priest before He can be the reigning King. This thought of His priesthood must have been especially borne in upon Him now that He had just reached the priestly age. In His thirteenth year--the Temple age--He had gone to the Temple, and now at the age when the priest is consecrated to his office, He is summoned to the Jordan, to be baptised by one whom He knows to be sent of God to prepare the way before Him. Those Scriptures, then, which speak of the priestly office the Messiah must fill, must have been very much in His mind as He came to John and offered Himself to be baptised. And of all these Scriptures none would seem more appropriate at the moment than those words of the fortieth Psalm: "Lo, I come: in the volume of the book it is written of Me, I delight to do Thy will, O My God."
At this point we can readily see the appropriateness of His baptism, and also an element in common between it and that of the people. They had come professing to be willing to do the will of God by turning from sin to righteousness. He had no need to turn from sin to do the will of God; but He had to turn from the quiet and peaceful home life at Nazareth, that He might take up the burden laid upon Him as Messiah. So He as well as they had to leave the old life and begin a new one; and in this we can see how fitting it was that He as well as they should be baptised. Then, just as by baptism--the symbol, in their case, of separation from sin and consecration to God--John made "ready a people prepared for the Lord;" so by baptism--the symbol, in His case, of separation from private life and consecration to God in the office of Messiah,--the Lord was made ready for the people. By baptism John opened the door of the new Kingdom. From the wilderness of sin the people entered it as subjects; from the seclusion of private life Jesus entered it as King and Priest. They came under a vow of obedience unto Him; He came under a vow of obedience unto death, even the death of the Cross.
