This lesson is on Acts 3:1-11, Peter's healing (with John) of a lame man (who had never walked) at the Beautiful Gate, begging for alms.  To his plea, Peter spoke the famous words, "Silver and gold have I none, but such as I have give I thee.  In the name of Jesus Christ of Nazareth rise up and walk" - and the man who had never stood on his own legs before, much less know how to walk, immediately leaped up, walked, went into the Temple walking, leaping, and praising God!  Isn't it wonderful the former lame man knew to whom the praise belonged?  He did not kiss the hand of Peter; nor did he even praise Peter.  His praise went to the Lord, Who the man knew and understood had done the healing through His servants! 

"The power was Christ's, but the hand was Peter's" (Thomas Walker).  This was the Lord continuing His work on earth through His Church by His Spirit.  This was an Apostolic miracle.  This miracle confirmed the great sermon he had just preached (his first, and the first of the Church Age).  Remember - the miracle confirmed the message, and it was the message that produced the fruit!
