Acts 4:13, 19-20

Now as they observed the confidence of Peter and John and understood that they were uneducated and untrained men, they were amazed, and began to recognize them as having been with Jesus…

19 But Peter and John answered and said to them, “Whether it is right in the sight of God to give heed to you rather than to God, you be the judge; 20 for we cannot stop speaking about what we have seen and heard.” 

This text, as you can see, comes directly after Peter’s reply to the Jewish leaders (verses 8-12). Their amazement was not so much that they were involved in a miraculous healing, but rather that they, being uneducated, could speak so well; and they recognized that they spoke with the same authority as Jesus; and thus, they perceived that it was because they spent so much time with Him. To this we also must be amazed and recognize that our best knowledge and learning will come by being around godly people—in addition to reading and memorizing Scripture.

In verses 14 through 18, we have what we may call a conundrum among the leaders. They didn’t know what to do with the evidence of the healing and all of what Peter and John said. But it was certain that they could not allow what had happened to continue.

Why? I suppose because they feared what would happen to their own ruling power. And certainly, Satan was controlling them. But Peter and John knew what to do. They knew that God was a greater authority. They must obey God rather than men; they must continue to speak all the words of God and to obey Him.
