"The emphasis in Stephen’s life is on fullness: he was full of the Holy Spirit and wisdom (Acts 6:3, 10), full of faith (Acts 6:5), and full of power (Acts 6:8). In Scripture, to be 'full of' means 'to be controlled by.' (Stephen) was controlled by the Spirit, faith, wisdom, and power. He was a God-controlled man yielded to the Holy Spirit, a man who sought to lead people to Christ." -Warren Wiersbe
