Acts 3:16

“And by faith in his name has his name made this man strong, whom you behold and know: yes, the faith which is through him has given him this perfect soundness in the presence of you all.”

And the fact that He had been raised and was truly the Prince of Life, and the Holy and Righteous One, was evidenced by the fact that it was His Name, as a result of faith in His Name, which had made this man strong. It was He who had healed the lame. None other could have done it. What has happened has established once for all His essential worth and power, through which this was accomplished. This once lame man was the evidence to all of Who and What Jesus was, and to the power of His being.

The faith here might signify the faith of Peter and John or it may be the faith of the lame man that is in mind. But the emphasis is on neither of these. The emphasis is rather on the One Whose Name may be totally relied on, and Who in response to faith can act in this way.

But it had nevertheless required faith, both from the Apostles and from the lame man. And the faith that they had and the faith that the man had received was ‘through Him'. It had come from the Lord Himself. And that is why it has given him this ‘perfect soundness (wholeness, completeness)'. This echoes the idea in Acts 3:7 above. The hint is that all who hear Him can also find perfect soundness in Him if they turn to Him in faith. All can be restored to full wholeness. It is in the light of this that the later appeal to repentance can be made (Acts 3:19).

In Greek the sentence is rather complicated, but by no means impossible. There is no reason for avoiding its plain sense. It is structured so as to place the emphasis on Him, and then on the faith that is required in order to benefit from Who He is..
