In the first place, the user of the phrase either defines the change of mind he means as one that has for its object the pardon of God, or as one that reaches to a new life: the latter seems to me the more natural interpretation by far. The kind and scope of the repentance or change, and not any end to be gained by it, appears intended. The change must be one of will and conduct--a radical change of life on the part of the man: he must repent--that is, change his mind--not to a different opinion, not even to a mere betterment of his conduct--not to anything less than a sending away of his sins. This interpretation of the preaching of the Baptist seems to me, I repeat, the more direct, the fuller of meaning, the more logical. Next, in St Matthew's gospel, the Baptist's buttressing argument, or imminent motive for the change he is pressing upon the people is, that the kingdom of heaven is at hand: 'Because the king of heaven is coming, you must give up your sinning.' The same argument for immediate action lies in his quotation from Isaiah,--'Prepare ye the way of the Lord; make straight in the desert a highway for our God.' The only true, the only possible preparation for the coming Lord, is to cease from doing evil, and begin to do well--to send away sin. They must cleanse, not the streets of their cities, not their houses or their garments or even their persons, but their hearts and their doings. It is true the Baptist did not see that the kingdom coming was not of this world, but of the higher world in the hearts of men; it is true that his faith failed him in his imprisonment, because he heard of no martial movement on the part of the Lord, no assertion of his sovereignty, no convincing show of his power; but he did see plainly that righteousness was essential to the kingdom of heaven. That he did not yet perceive that righteousness _is_ the kingdom of heaven; that he did not see that the Lord was already initiating his kingdom by sending away sin out of the hearts of his people, is not wonderful. The Lord's answer to his fore-runner's message of doubt, was to send his messenger back an eye-witness of what he was doing, so to wake or clarify in him the perception that his kingdom was not of this world--that he dealt with other means to another end than John had yet recognized as his mission or object; for obedient love in the heart of the poorest he healed or persuaded, was his kingdom come. Again, observe that, when the Pharisees came to John, he said to them, 'Bring forth therefore fruits meet for repentance:' is not this the same as, 'Repent unto the sending away of your sins'?
