In this chapter we have a miracle and a sermon: the miracle wrought to make way for the sermon, to confirm the doctrine that was to be preached, and to make way for it into the minds of the people; and then the sermon to explain the miracle, and to sow the ground which by it was broken up. I. The miracle was the healing of a man that was lame from his birth, with a word speaking (Act 3:1-8), and the impression which this made upon the people (Act 3:9-11). II. The scope of the sermon which was preached hereupon was to bring people to Christ, to repent of their sin in crucifying him (Act 3:12-19), to believe in him now that he was glorified, and to comply with the Father's design in glorifying him (Act 3:20-26). The former part of the discourse opens the wound, the latter applies the remedy.
