Acts 4:13 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.

Acts 4:31 And when they had prayed, the place where they had gathered together was shaken, and they were all filled with the Holy Spirit and began to speak the word of God with boldness.

Acts 14:3 Therefore they spent a long time there speaking boldly with reliance upon the Lord, who was testifying to the word of His grace, granting that signs and wonders be done by their hands.

Philippians 1:14 and that most of the brethren, trusting in the Lord because of my imprisonment, have far more courage to speak the word of God without fear. (NASB ©1995)
