During the period of our Lord's retirement in the wilderness the Baptist continued his ministry, crying repentance to all who would pause to hear, and administering baptism to such as came duly prepared and asking with right intent. The people generally were greatly concerned over the identity of John; and as the real import of the voice[309] dawned upon them, their concern deepened into fear. The ever recurring question was, Who is this new prophet? Then the Jews, by which expression we may understand the rulers of the people, sent a delegation of priests and Levites of the Pharisaic party to personally question him. He answered without evasion, "I am not the Christ," and with equal decisiveness denied that he was Elias, or more accurately, Elijah, the prophet who, the rabbis said through a misinterpretation of Malachi's prediction, was to return to earth as the immediate precursor of the Messiah.[310] Furthermore, he declared that he was not "that prophet," by which was meant the Prophet whose coming Moses had foretold,[311] and who was not universally identified in the Jewish mind with the expected Messiah. "Then said they unto him, Who art thou? that we may give an answer to them that sent us. What sayest thou of thyself? He said, I am the voice of one crying in the wilderness, Make straight the way of the Lord, as said the prophet Esaias."[312] The Pharisaic envoys then demanded of him his authority for baptizing; in reply he affirmed that the validity of his baptisms would be attested by One who even then was amongst them, though they knew Him not, and averred: "He it is, who coming after me is preferred before me, whose shoe's latchet I am not worthy to unloose."[313] John's testimony, that Jesus was the Redeemer of the world, was declared as boldly as had been his message of the imminent coming of the Lord. "Behold the Lamb of God, which taketh away the sin of the world," he proclaimed; and, that none might fail to comprehend his identification of the Christ, he added: "This is he of whom I said, After me cometh a man which is preferred before me: for he was before me. And I knew him not: but that he should be made manifest to Israel, therefore am I come baptizing with water."[314] That the attestation of the ministering presence of the Holy Ghost through the material appearance "like a dove" was convincing to John is shown by his further testimony: "And John bare record saying, I saw the Spirit descending from heaven like a dove, and it abode upon him. And I knew him not: but he that sent me to baptize with water, the same said unto me, Upon whom thou shalt see the spirit descending, and remaining on him, the same is he which baptizeth with the Holy Ghost. And I saw, and bare record that this is the Son of God."[315] On the day following that of the utterance last quoted, John repeated his testimony to two of his disciples, or followers, as, Jesus passed, saying again: "Behold the Lamb of God."[316]
