What does Acts 3:9-12 mean?

9 And all the people saw him walking and praising God: 10 And they knew that it was he which sat for alms at the Beautiful gate of the temple: and they were filled with wonder and amazement at that which had happened unto him. 11 And as the lame man which was healed held Peter and John, all the people ran together unto them in the porch that is called Solomon’s, greatly wondering. 12 And when Peter saw it, he answered unto the people, Ye men of Israel, why marvel ye at this? or why look ye so earnestly on us, as though by our own power or holiness we had made this man to walk? (Acts 3:9-12 KJV)

William Burkitt’s Commentary

Observe here, 1. As soon as ever the poor cripple received strength, all the people beheld him praising and blessing God.-

Learn hence, That the very first appearances of the power and mercy of God, towards ourselves or any of ours, should put us upon the works of praise and rejoicing. We truly say, “Better late than never;” but it is best to be early in every good work, especially in the noblest and most angelical work; namely, that of thanksgiving and praise. My voice shalt thou hear, says David, betimes in the morning: my praying voice, my praising voice.

Observe, 2. The influence and effect that this miracle had upon the minds of the multitude. ; it occasioned wonder, but did not produce faith. They wondered, but not believed. Miracles will confirm faith, but not alone beget it. The Spirit’s extraordinary works may produce astonishment; but it is the work of the Spirit that must produce faith.

Observe, 3. How the apostle abaseth himself and his fellow disciples, that he might exalt Christ; he will not suffer the least part of the praise and glory of this miracle to stick to their own fingers, but gives it all to Christ. Think not that we by pure power and holiness have made this man to walk. The Jews had a conceit, that extraordinary holiness would enable a man to work miracles: The apostle denies it: For though there be a great difference betwixt miraculous faith and justifying faith, ye true justifying faith has a miracle in it, though not so obvious to sense, requiring the same power to work it in us, which raised up Christ from the dead, Ephesians 1:20.

Learn hence, That Christ’s power, not is apostles’ holiness, was the cause of all the miracles that were wrought by them. Why look you so earnestly upon us, as though by our holiness we had made this man to walk? Through faith in his name, is this man made strong, Acts 3:16.
