Luke 3:4

The law, indeed, had to be overthrown, from the moment when John "cried in the wilderness, Prepare ye the ways of the Lord," that valleys and hills and mountains may be filled up and levelled, and the crooked and the rough ways be made straight and smooth -in other words, that the difficulties of the law might be changed into the facilities of the gospel.

John holds not his peace, saying, "Enter upon repentance, for now shall salvation approach the nations" -the Lord, that is, bringing salvation according to God's promise.

(non occ.) And because a path is a way trodden down by those that have gone before, and which former men have worn away, the word bids those who depart from the zeal of their predecessors repeatedly pursue it.

John, being chosen for the apostleship, was also the last of the holy prophets. For this reason, as the Lord has not come yet, he says, "Prepare the way of the Lord." What is the meaning of "Prepare the way of the Lord"? It means, Make ready for the reception of whatever Christ may wish to do. Withdraw your hearts from the shadow of the law, discard vague figures and no longer think perversely. Make the paths of our God straight. For every path that leads to good is straight and smooth and easy, but the one that is crooked leads down to wickedness those that walk in it.

(ubi sup.) But to cry, Prepare ye the way of the Lord, was not the office of the king, but of the forerunner. And so they called John the voice, because he was the forerunner of the Word.

See, at least, how both the prophet and the Baptist go upon the same ideas, although not upon the same words. Thus the prophet saith that he shall come saying, "Prepare ye the way of the Lord, make his paths straight." And he himself when he was come said, "Bring forth fruits meet for repentance," which corresponds with, "Prepare ye the way of the Lord." Seest thou that both by the words of the prophet, and by his own preaching, this one thing is manifested alone; that he was come, making a way and preparing beforehand, not bestowing the gift, which was the remission, but ordering in good time the souls of such as should receive the God of all?

Again, the wilderness is the Church itself, for the barren has more children than she who has an husband. The word of the Lord came, that the earth which was before barren might bring forth fruit unto us.

As it is written etc. Here the authority of John is commended from the prophetic attestation, in which John preaching is shown to have the office of arousing, admonishing, and consoling. — He is shown, I say, first to have the office of arousing through …

"I am the voice of one crying in the wilderness: Make straight the way of the Lord, as Isaiah the prophet said." You know, dearest brothers, that the only-begotten Son is called the Word of the Father, as John testifies when he says: "In the beginning was the Word, and the Word was with God, and the Word was God." And from your own manner of speaking you recognize that the voice sounds first, so that the word may afterward be heard. Therefore John asserts that he is the voice, because he precedes the Word. And so, going before the coming of the Lord, he is called a voice, because through his ministry the Word of the Father is heard by men. He also cries out in the wilderness, because he announces the comfort of the Redeemer to abandoned and forsaken Judea. But what he cries out he indicates when he adds: "Make straight the way of the Lord." The way of the Lord is made straight to the heart when the word of truth is humbly heard. The way of the Lord is made straight to the heart when one's life is prepared according to his commandment.

As it is written in the book of the words of Isaiah the prophet: The voice of one crying in the wilderness, Prepare the way of the Lord, make his paths straight. Indeed, the same John the Baptist, when asked who he was, answered, saying: I am the voice of one crying in the wilderness. He, as was said by us before, was called a voice by the prophet because he preceded the Word. But what he cried out is revealed when it is added: Prepare the way of the Lord, make his paths straight. Everyone who preaches right faith and good works, what else does he do but prepare a way for the coming Lord into the hearts of his hearers? So that the power of grace may penetrate, so that the light of truth may illuminate, so that he may make straight paths for God, while he forms pure thoughts in the mind through the word of good preaching.

The "way" which he commands to prepare is the manner of life according to the teaching of Christ, for the Lord was soon to preach. The "paths" are the commandments of the Law, as if already worn away. He commands to make them "straight" because …

As it is written in the book of the words of Isaiah the prophet: The voice, etc. The same John the Baptist, being asked who he was, answered, I am the voice of one crying in the wilderness, who is therefore called a voice by …

(7, 20. in Ev.) John cries in the desert because he brings the glad tidings of redemption to deserted and forsaken Judæa, but what he cries is explained in the words, Prepare ye the way of the Lord. For they who preach true faith and good works, what else do they than prepare the way for the Lord's coming into the hearts of the hearers, that they might make the paths of God straight, forming pure thoughts in the mind by the word of good preaching.

As it is written in the book of the words of Esaias the prophet,.... Isa 40:3 saying, the voice of one crying in the wilderness, Prepare ye the way of the Lord make his paths straight; See Gill on Mat 3:3.

Prepare ye the way - It was customary for the Hindoo kings, when on journeys, to send a certain class of the people two or three days before them, to command the inhabitants to clear the ways. A very necessary precaution where there are no public roads. - Ward.

These verses describe the beginning of the Gospel of Christ. It began with the preaching of John the Baptist. The Jews could never say, that when Messiah came, He came without notice or preparation. He graciously sent a mighty forerunner before His face, by whose ministry the attention of the whole nation was awakened. Let us notice first, in this passage — the wickedness of the times when Christ's Gospel was brought into the world.

These verses describe the beginning of the Gospel of Christ. It began with the preaching of John the Baptist. The Jews could never say, that when Messiah came, He came without notice or preparation. He graciously sent a mighty forerunner before His face, by whose ministry the attention of the whole nation was awakened. Let us notice first, in this passage — the wickedness of the times when Christ's Gospel was brought into the world. The opening verses of the chapter tell us the names of some who were rulers and governors in the earth, when the ministry of John the Baptist began. It is a melancholy list, and full of instruction. There is hardly a name in it which is not infamous for wickedness . Tiberius, and Pontius Pilate, and Herod, and his brother, and Annas, and Caiaphas — were men of whom we know little or nothing but evil. The earth seemed given into the hands of the wicked. (Job 9:24.) When such were the rulers — then what must the people have been? Such was the state of things when Christ's forerunner was commissioned to begin preaching. Such were the times when the first foundation of Christ's church was brought out and laid. We may truly say, that God's ways are not our ways. Let us learn never to despair about the cause of God's truth — however black and unfavorable its prospects may appear . At the very time when things seem hopeless — God may be preparing a mighty deliverance. At the very season when Satan's kingdom seems to be triumphing, the "little stone, cut without hands," may be on the point of crushing it to pieces. The darkest hour of the night — is often that which just precedes the day. Let us beware of slackening our hands from any work of God, because of the wickedness of the times , or the number and power of our adversaries. "He who observes the wind shall not sow — and he who regards the clouds shall not reap."
