Raphael, Saint John the Baptist Preaching (National Gallery), 1505

THE Holy Baptist was sent before our Lord to prepare His way; that is, to be His instrument in rousing, warning, humbling, and inflaming the hearts of men, so that, when He came, they might believe in Him. He Himself is the Author and Finisher of that Faith, of which He is also the Object; but, ordinarily, He does not implant it in us suddenly, but He first creates certain dispositions, and these He carries on to faith as their reward. When then He was about to appear on earth among His chosen people, and to claim for Himself their faith, He made use of St. John first to create in them these necessary dispositions.

Now these passages cannot mean that faith is against reason, or that reason does not ordinarily precede faith, for this is a doctrine quite contrary to Revelation, but I think I shall not be wrong in understanding them thus,—that with good dispositions faith is easy; and that without good dispositions, faith is not easy; and that those who were praised for their faith, were such as had already the good dispositions, and that those who were blamed for their unbelief, were such as were wanting in this respect, and would have believed, or believed sooner, had they possessed the necessary dispositions for believing, or a greater share of the them. This is the point I am going to insist on: I am led to it by the Baptist's especial office of "preparing the way of the Lord"; for by that preparation is meant the creating in the hearts of his hearers the dispositions necessary for faith. And I consider that the same truth is implied in the glorious hymn of the Angels upon Christmas night; for to whom was the Prince of Peace to come? They sang, "Glory to God in the highest, and on earth peace to men of good will." By "good will" is meant, "good disposition"; the peace of the Gospel, the full gifts of the knowledge, and of the power, and of the consolation of Christian Redemption, were to be the reward of men of good dispositions. They were the men to whom the Infant Saviour came; they were those in whom His grace would find its fruit and recompense; they were those, who, by congruous merit, would be led on, as the Evangelist says, to "believe in His Name," and "to be born, not of blood, nor of the will of the flesh, nor of the will of man, but of God."
