(16) His name through faith in his name.--We have, in technical language, the efficient cause distinguished from the indispensable condition of its action. The Name did not work as a formula of incantation; it required, on the part both of the worker and the receiver, faith in that which the Name represented, the manifestation of the Father through the Son.

Hath made this man strong.--The verb is the same as that which had been used in Acts 3:7 of the "feet and ankle-bones." It was Jesus who had given them that new firmness.

The faith which is by him.--The causation of the miracle is carried yet another step backward. The faith which was alike in the healer and in the man healed was itself wrought in each by the power of Christ. The man was first a willing recipient of that faith spiritually, and then was in a state that made him worthy to be a recipient also of the bodily restoration.

This perfect soundness.--Literally, this completeness. This is the only passage in the New Testament in which the word occurs. The cognate adjective is found in the "whole" of 1Thessalonians 5:23; the "complete" of James 1:4.

Verse 16. - By faith in his Name hath this for his Name through faith in his Name, A.V.: the order of the words is changed from that of the A.V., to bring it into accordance with the order of the Greek, but with a great loss of force in English; behold for see, A.V.; through for by, A.V. Yea, the faith; rather, and the faith. The two propositions are not the same. The first affirms that it is the Name of Jesus which has given him strength, objectively; the second that the faith (subjective) which is through or by him hath given him perfect soundness. There is some obscurity in the exact meaning of ἡ πίστις ἡ δι αὐτοῦ. Some (see Alford, 1:1) compare 1 Peter 1:21, and make God the object of the faith of his witnesses, Peter and John. Others (Meyer) understand that the faith in the Name of Christ was wrought in Peter and John by or through Christ's ministry and resurrection. But it is much more consonant with other passages (Acts 14:9; Acts 16:31, etc.; Matthew 15:28, etc.) to understand the faith to be that of the man who was healed; and then the phrase, "which is through him," will denote naturally that it was through Jesus Christ that the man's faith brought him into contact, so to speak, with God who healed him. In the same spirit we read that the lame man "praised God" (vers. 8, 9) for the cure effected through the Name of Jesus Christ; and Peter says (ver. 15), "Whom God raised from the dead." The interpretation of the phrase ἡ δι αὐτοῦ depends upon whether we supply an active or a passive word. The faith which acts, or works, or moves through him is one way of understanding it; the faith which is wrought or produced through him is the other. The first is preferable. This perfect soundness; pointing to what they saw with their own eyes while the man was leaping and dancing before them (ὁλοκληρία, perfect soundness, used only here in the New Testament; it is a medical term).

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.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.
