And his name - The "name" of Jesus is here put for Jesus himself, and it is the same as saying "and he," etc. In this way the word name is often used by the Hebrews, especially when speaking of God, Acts 1:15; Acts 4:12; Ephesians 1:21; Revelation 3:4. It does not mean that there was any efficacy in the mere name of Jesus that would heal the man, but that it was done by his authority and power.

Through faith in his name - By means of faith in him; that is, by the faith which Peter and John had in Jesus. It does not refer to any faith that the man had himself, for there is no evidence that he believed in him. But it was by means of the faith which the apostles exercised in him that the miracle was performed, and was thus a fulfillment of the declaration in Matthew 17:20, "If ye have faith ...ye shall to this mountain, remove hence," etc. This truth Peter repeats two or three times in the verse to impress it more distinctly on the minds of his hearers.

Whom ye see and know - There could therefore, be no mistake. He was well known to them. There was no doubt about the truth of the miracle Acts 4:16, and the only inquiry was in what way it had been done. This Peter affirms to have been accomplished only by the power of the Lord Jesus.

Perfect soundness - ὁλοκληρίαν holoklērian. This word is not used elsewhere in the New Testament. It denotes "integrity of parts, freedom from any defect"; and it here means that the cure was perfect and entire, or that he was completely restored to the use of his limbs.

In the presence of you all - You are all witnesses of it, and can judge for yourselves. This shows how confident the apostles were that a real miracle had been performed. They were willing that it should be examined; and this is conclusive proof that there was no attempt at imposture. A deceiver, or one who pretended to work miracles, would have been cautious of exposing the subject to the danger of detection.

And his name - Jesus, the Savior: through faith in his name, as the Savior, and author of life, and all its concomitant blessings, such as health, etc. It is not quite clear whether the apostles refer to their own faith in Jesus, or to the faith of the lame man. It is true Christ had promised that they should perform miracles in his name, Mark 16:17, Mark 16:18. And that whatsoever they asked of the Father in his name, he would grant it, John 16:23. And they might have been led at this time to make request unto God to be enabled to work this miracle; and the faith they had in his unlimited power and unchangeable truth might have induced them to make this request. Or, the faith might have been that of the lame man; the apostles, in the time they desired him to look on them, might have taught him the necessity of believing in Christ in order to his healing; and the man's mind might have been prepared for this by the miracle of the gift of tongues, of which he must have heard; and heard that this mighty effusion of the Spirit had come in the name and through the power of Christ. However the faith may be understood, it was only the means to receive the blessing, which the apostles most positively attribute, not to their power or holiness, but to Jesus Christ alone. Faith always receives; never gives.

And his name, through faith in his name,.... That is, the name of Christ, or the power of Christ, through the faith of the apostles in him, while they made use of his name, and said, "in the name of Jesus Christ of Nazareth", &c. Acts 3:6 or Christ, through the faith of the lame man in him; and when his name was used in this manner by the apostles; not that either their faith, or his, had any causal influence on the cure, but was the way and means in which they, glorifying Christ, he was pleased to effect this cure:

hath made this man strong; who was before exceeding weak; strengthened the parts that were infirm, his feet and ankles, and consolidated them, so that he could use them, and walk with them:

whom ye see and know; they knew him before, when he was lame, and now knew him to be the same man, and whom they saw now perfectly well; so that they could be appealed to that there was no fraud or imposture in the case:

yea, the faith which is by him; by Christ, of which he is the object, and the author, and finisher: this is repeated out of affection to Christ, and a passionate concern for the glory of his name; or because that faith, in one clause, may regard the faith of the apostles, and in the other, the faith of the man that was cured:

hath given him this perfect soundness in the presence of you all: he had perfect soundness both in body and mind; though the former may chiefly be designed, it being that which was only visible to these persons; and which was done, not in a corner, but publicly, before them all, at the gate of the temple, where the multitude passed to and fro.

Through faith (ἐπὶ τῇ πίστει)

Note the article: the faith which we had; not the cripple's faith, which was not demanded as a condition of his cure. Through faith (ἐπί) is rather on account of, or on the basis of. Rev., by. Compare Acts 2:38; and see on Matthew 28:19.

Made strong (ἐστερέωσε)

See on Acts 3:7.

Ye see (θεωρεῖτε)

See on Luke 10:18.

Perfect soundness (ὁλοκληρίαν)

Only here in New Testament. From ὅλος, entire, and κλῆρος, a lot. Denoting, therefore, the condition of one who has his entire allotment.

And his name through faith in his name hath made this man strong, whom ye see and know: {d} yea, the faith which is by him hath given him this perfect soundness in the presence of you all.

(d) Because he believed on him who was raised from the dead, whose name he heard about from us.

3:16 His name. Not Peter's power, but Christ's name, had done all.

Through faith in his name. Not only the faith of Peter and John, but the faith created in the lame man. In an act of faith he was made strong. Plumptree states:

The faith alike is in the healer and the healed.''

3:16 His name - Himself: his power and love. The faith which is by him - Of which he is the giver, as well as the object.

16. his name, through faith in his name, hath made this man strong, &c.-With what skill does the apostle use the miracle both to glorify his ascended Lord and bring the guilt of His blood more resistlessly home to his audience!

3:12-18 Observe the difference in the manner of working the miracles. Our Lord always spoke as having Almighty power, never hesitated to receive the greatest honour that was given to him on account of his Divine miracles. But the apostles referred all to their Lord, and refused to receive any honour, except as his undeserving instruments. This shows that Jesus was one with the Father, and co-equal with Him; while the apostles knew that they were weak, sinful men, and dependent for every thing on Jesus, whose power effected the cure. Useful men must be very humble. Not unto us, O Lord, not unto us, but to thy name, give glory. Every crown must be cast at the feet of Christ. The apostle showed the Jews the greatness of their crime, but would not anger or drive them to despair. Assuredly, those who reject, refuse, or deny Christ, do it through ignorance; but this can in no case be an excuse.
