In Acts 3, Peter and John are used of God to heal a man lame from birth. They then take the opportunity to share the Gospel to everyone who saw the miracle. Because of their teaching and preaching they greatly annoyed the Sadducees and temple people, so Peter and John were arrested (chapter four).
“Now when they saw the boldness of Peter and John, and perceived that they were uneducated, common men, they were astonished. And they recognized that they had been with Jesus.” -Acts 4:13
What comfort and encouragement oozed out of this passage for me. They were uneducated (in the Rabbinical schools) and were common. Yet they were used so powerfully by God (because of their boldness) so that the high priests were astonished and saw and recognized they had been with Jesus, for there was no other explanation.
The high priests end up letting them go even after Peter and John tell them they won’t stop speaking about the Lord. Why did they let them go?
“(They let them go) finding no way to punish them, because of the people, for all were praising God for what had happened.” -Acts 4:21
