Evidently, Stephen was viewed by others as being a man of maturity. He didn't overreact to things. He was temperate and moderate and mature, and when he spoke it was with wisdom. I've observed that in trying to hang on to his youth, many a man manages to hang on to his foolishness and immaturity. But when you see Stephen, you see a young man whose wisdom exceeded his years.
Many men are highly defensive, impulsive, swift to react.
Stephen, on the other hand, responded to difficulties and opportunities with steady, measured maturity and gained the respect of his hearers. Many men today lack self-discipline. That's why so many men, perhaps even some in this room, have been lured by the devil into internet pornography, and you think no one knows about it except you. But the devil knows, the Lord knows, and there may be other people who know. Our computers are never quite as private as we think they are.
