Peter’s declaration to a skeptical — if not hostile — audience is not made with malice. It is made as a faithful testimony to the scriptures and to the evidence of God’s work in our time.
Each day, we have an opportunity akin to Peter and John’s, as recorded in today’s reading. If we are diligent students of God’s written word, and vigilant for his presence, we will have numerous occasions to give faithful testimony.
People may dispute the former, and discount the latter; but our role as Christian disciples is to give faithful testimony remains. – Luther
