The spirit of his demands was that of a practical religion, the only religion of any possible worth--the religion of right living. With all his vigor, in spite of his brusqueness, notwithstanding his forceful assaults on the degenerate customs of the times, this John was no agitator against established institutions, no inciter of riot, no advocate of revolt, no promoter of rebellion. He did not assail the tax system but the extortions of the corrupt and avaricious publicans; he did not denounce the army, but the iniquities of the soldiers, many of whom had taken advantage of their position to bear false witness for the sake of gain and to enrich themselves by forcible seizure. He preached, what in the now current dispensation we call the first or fundamental principles of the gospel--"the beginning of the gospel of Jesus Christ, the Son of God,"[286] comprizing faith, which is vitalized belief, in God; genuine repentance, which comprizes contrition for past offenses and a resolute determination to turn from sin; baptism by immersion in water at his hands as the hands of one having authority; and the higher baptism by fire or the bestowal of the Holy Ghost by an authority greater than that possessed by himself. His preaching was positive, and in many respects opposed to the conventions of the times; he made no appeal to the people through the medium of miraculous manifestations;[287] and though many of his hearers attached themselves to him as disciples,[288] he established no formal organization, nor did he attempt to form a cult. His demand for repentance was an individual call, as unto each acceptable applicant the rite of baptism was individually administered. To the Jews, who were living in a state of expectancy, waiting for the long-predicted Messiah, the words of this strange prophet in the wilderness were fraught with deep portent. Could it be that he was the Christ? He spoke of One yet to come, mightier than himself, whose shoe-latchet he was not worthy to loosen,[289] One who would separate the people as the thresher, fan in hand, blew the chaff from the wheat; and, he added, that mightier One "will gather the wheat into his garner; but the chaff he will burn with fire unquenchable."[290] In such wise did the predicted herald of the Lord deliver his message. Himself he would not exalt; his office, however, was sacred to him, and with its functions he brooked no interference from priest, Levite, or rabbi. He was no respecter of persons; sin he denounced, sinners he excoriated, whether in priestly vestments, peasant garb, or royal robes. All the claims the Baptist had made for himself and his mission were later confirmed and vindicated by the specific testimony of Christ.[291] John was the harbinger not alone of the kingdom but of the King; and to him the King in person came.
