3:12 {2} 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?
(2) Miracles are appointed to convince the unbelievers, and therefore they wickedly abuse the miracles who, standing amazed, either at the miracles themselves or at the instruments and means which is pleases God to use, take an occasion to establish idolatry and superstition by that which God has provided for the knowledge of his true worship, that is, Christianity.
3:12 Ye men of Israel. Peter seized the opportunity to preach Christ.
3:12 Peter answered the people - Who were running together, and inquiring into the circumstances of the fact.
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.
