“Prepare your minds for action,” to Peter meant, “Gird up your loins mentally”…which in modern terminology might mean, “Fasten your seatbelts,” or “Roll up your sleeves.” This phrase of Peter’s was a metaphor for preparing oneself mentally for action and readiness for the challenges ahead as a Christian in this broken world. For Peter knew what it was like to boldly follow Jesus in the face of persecution, and is urging us today to prepare for vigorous and sustained spiritual exertion by living a God-centered life that reflects our faith…which is the only way we can set our hope fully on the grace to be given us when Jesus Christ makes His return.
