1-10: Notice the obvious supernatural nature of the healing. The man had been lame from birth, and others brought him up to beg. The people recognized who he was and the amazing miracle that had been performed. It helps that the man immediately began leaping and praising God!
11-26: Peter uses the occasion to preach a sermon. He declares that what was done was not done in his own power, but the power of God. He reminds them that they rejected Jesus, but God vindicated His ministry by glorifying Him, and it was all a part of God’s plan. In fact, God is once again revealing the truth about Jesus and their need to know Him by allowing Peter and John to heal in His name. They need to repent because Jesus is coming back, and they should want to be a part of His kingdom! Jesus is the prophet like Moses (Deuteronomy 18:15) whom they need to obey (Deuteronomy 18:19). It is through Him that all the nations of the earth will be blessed (Genesis 22:18)!
There are two themes in these verses which align Peter with two other theological New Testament giants (which shows how the Holy Spirit was inspiring all of them). First, Peter calls Jesus the “Originator of life,” mirroring what John says:
John 1:3 “All things were created by him, and apart from him not one thing was created that has been created.”
And by his quote of Genesis 22:18, he shows agreement with Paul:
Galatians 3:8 “And the scripture, foreseeing that God would justify the Gentiles by faith, proclaimed the gospel to Abraham ahead of time, saying, ‘All the nations will be blessed in you.’”
We would do well to acknowledge God’s fingerprints throughout Scripture. And, according to our passage, we acknowledge God by: admitting our sin, believing in the Savior, obeying His Word, and rejoicing because of our salvation!
