(2.) To give people a general idea of the salvation, that they might know, not only what to do, but what to expect; for the doctrine he preached was that the kingdom of heaven is at hand. There are two things in which you must know that this salvation consists:—
[1.] The forgiveness of what we have done amiss. It is salvation by the remission of sins, those sins which stand in the way of the salvation, and by which we are all become liable to ruin and condemnation, v. 77. John Baptist gave people to understand that, though their case was sad, by reason of sin, it was not desperate, for pardon might be obtained through the tender mercy of our God (the bowels of mercy, so the word is): there was nothing in us but a piteous case to recommend us to the divine compassion.
[2.] Direction to do better for the time to come. The gospel salvation not only encourages us to hope that the works of darkness shall be forgiven us, but sets up a clear and true light, by which we may order our steps aright. In it the day-spring hath visited us from on high (v. 78); and this also is owing to the tender mercy of our God. Christ is anatole—the morning Light, the rising Sun, Mal. iv. 2. The gospel brings light with it (John iii. 19), leaves us not to wander in the darkness of Pagan ignorance, or in the moonlight of the Old-Testament types or figures, but in it the day dawns; in John Baptist it began to break, but increased apace, and shone more and more to the perfect day. We have as much reason to welcome the gospel day who enjoy it as those have to welcome the morning who had long waited for it. First, The gospel is discovering; it shows us that which before we were utterly in the dark about (v. 79); it is to give light to them that sit in darkness, the light of the knowledge of the glory of God in the face of Jesus Christ; the day-spring visited this dark world to lighten the Gentiles, Acts xxvi. 18. Secondly, It is reviving; it brings light to them that sit in the shadow of death, as condemned prisoners in the dungeon, to bring them the tidings of a pardon, at least of a reprieve and opportunity of procuring a pardon; it proclaims the opening of the prison (Isa. lxi. 1), brings the light of life. How pleasant is that light! Thirdly, It is directing; it is to guide our feet in the way of peace, into that way which will bring us to peace at last. It is not only a light to our eyes, but a light to our feet (Ps. cxix. 105); it guides us into the way of making our peace with God, of keeping up a comfortable communion; that way of peace which as sinners we have wandered from and have not known (Rom. iii. 17), nor could ever have known of ourselves.
In the last verse, we have short account of the younger years of John Baptist. Though he was the son of a priest, he did not, like Samuel, go up, when he was a child, to minister before the Lord; for he was to prepare the way for a better priesthood. But we are here told,
1. Of his eminence as to the inward man: The child grew in the capacities of his mind, much more than other children; so that he waxed strong in the spirit; had a strong judgment and strong resolution. Reason and conscience (both which are the candle of the Lord) were so strong in him that he had the inferior faculties of appetite and passion in complete subjection betimes. By this it appeared that he was betimes filled with the Holy Ghost; for those that are strong in the Lord are strong in spirit.
2. Of his obscurity as to the outward man: He was in the deserts; not that he lived a hermit; cut off from the society of men. No, we have reason to think that he went up to Jerusalem at the feasts, and frequented the synagogues on the sabbath day, but his constant residence was in some of those scattered houses that were in the wilderness of Zuph or Maon, which we read of in the story of David. There he spent most of his time, in contemplation and devotion, and had not his education in the schools, or at the feet of the rabbin. Note, Many a one is qualified for great usefulness, who yet is buried alive; and many are so long buried who are designed, and are thereby in the fitting, for so much greater usefulness at last; as John Baptist, who was in the desert only till the day of his showing to Israel, when he was in the thirtieth year of his age. Note, There is a time fixed for the showing of those favours to Israel which are reserved; the vision of them is for an appointed time, and at the end it shall speak, and shall not lie.
