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--
And hope to the end - Margin, “perfectly.” The translation in the text is the most correct. It means that they were not to become faint or weary in their trials. They were not to abandon the hopes of the gospel, but were to cherish those hopes to the end of life, whatever opposition they might meet with, and however much might be done by others to induce them to apostatize. Compare the notes at Hebrews 10:35-36.
