In expectation - Expecting the Messiah. Margin, "suspense." That is, they were not certain whether John was not himself the Messiah. They confidently "expected" his appearing, and there minds were in "suspense," or they were in a state of doubt whether he had not already come, and whether John was not the Messiah.

Mused in their hearts of John - Thought of his character, his preaching, and his success, and anxiously inquired whether he did not do the things which were expected of the Messiah.

Whether he were the Christ - So general was the reformation which was produced by the Baptist's preaching that the people were ready to consider him as the promised Messiah. Thus John came in the spirit and power of Elijah, and reformed all things; showed the people, the tax-gatherers, and the soldiers, their respective duties, and persuaded them to put away the evil of their doings. See the note on Matthew 17:11.

And as the people were in expectation, of the coming of the Messiah; Daniel's seventy weeks being now accomplished, the sceptre being departed from Judah, and the Romans having the government in their hands, from whom they hoped for a deliverance by Christ;

and all men mused in their hearts of John; whether he were the Christ, or no; about which they had many reasonings and debates: some doubting of it, others ready to believe it, from his extraordinary birth, the singular holiness of his life, the power and efficacy of his doctrine, the new ordinance he administered, the restoration of religion by him, the freedom he took in reproving the vices of men, and the apt answers he gave to the questions now put to him. And that the Messiah was born, though he was not, as yet, made manifest, they might conclude, not only from the fulfilment of several prophecies, but from the song of Zacharias, the declaration of Simeon and Anna in the temple, and of the wise men that came from the east; and John appearing in such an unusual manner, they were ready to hope that he was the person; though they did not consider that he was of the tribe of Levi, and not of Judah; from which latter the Messiah was to spring; but this might be unattended to by them, and Satan might have an hand in it to hide the true Messiah from them.

Better as Rev., reasoned. Compare Luke 1:29; and see on James 2:4.

{2} And as the people were in expectation, and all men mused in their hearts of John, whether he were the Christ, or not;

(2) If we would rightly and fruitfully receive the sacraments, we must neither rest in the signs, neither in him that ministers the signs, but lift up our eyes to Christ, who is the author of the sacraments, and the giver of that which is represented by the sacraments.

15-17. whether he were the Christ-showing both how successful he had been in awakening the expectation of Messiah's immediate appearing, and the high estimation, and even reverence, which his own character commanded. (Also see on [1555]Mt 3:10.)

3:15-20 John the Baptist disowned being himself the Christ, but confirmed the people in their expectations of the long-promised Messiah. He could only exhort them to repent, and assure them of forgiveness upon repentance; but he could not work repentance in them, nor confer remission on them. Thus highly does it become us to speak of Christ, and thus humbly of ourselves. John can do no more than baptize with water, in token that they ought to purify and cleanse themselves; but Christ can, and will baptize with the Holy Ghost; he can give the Spirit, to cleanse and purify the heart, not only as water washes off the dirt on the outside, but as fire clears out the dross that is within, and melts down the metal, that it may be cast into a new mould. John was an affectionate preacher; he was beseeching; he pressed things home upon his hearers. He was a practical preacher; quickening them to their duty, and directing them in it. He was a popular preacher; he addressed the people, according to their capacity. He was an evangelical preacher. In all his exhortations, he directed people to Christ. When we press duty upon people, we must direct them to Christ, both for righteousness and strength. He was a copious preacher; he shunned not to declare the whole counsel of God. But a full stop was put to John's preaching when he was in the midst of his usefulness. Herod being reproved by him for many evils, shut up John in prison. Those who injure the faithful servants of God, add still greater guilt to their other sins.
