Therefore, prepare your minds for action,{Literally, "gird up the loins of your mind"} be sober and set your hope fully on the grace that will be brought to you at the revelation of Jesus Christ--
Hope to the end, or, Perfectly hope. He intimates that those who let their minds loose on vanity, did not really and sincerely hope for the grace of God; for though they had some hope, yet as they vacillated and were tossed to and fro in the world, there was no solidity in their hope. Then he says, for the grace which will be brought to you, in order that they might be more prompt to receive it. God ought to be sought, though far off; but he comes of his own will to meet us. How great, then, must be our ingratitude if we neglect the grace that is thus set before us! This amplification, then, is especially intended to stimulate our hope.
