Wherefore gird up the loins of your mind, be sober, and hope to the end for the grace that is to be brought unto you at the revelation of Jesus Christ;
Ver. 13. Wherefore gird up, &c.] We are seldom comforted, but we have need to be exhorted. So apt are our hearts to security, and so apt is Satan to interrupt our joys with his base injections. How soon did Hezekiah fondly overshoot himself to the Babylonish ambassadors, after his sweet intercourse with God in holy duties! And how shamefully did Jonah forget himself and break out into a brawl with God, after his embassage faithfully discharged to the Ninevites, and the sweet comforts that came in to his soul thereupon!
Gird up the loins of your mind, &c.] Gird yourselves and serve God, Luke 17:8. A loose, discinct, and diffluent mind is unfit for God's service. Girding implies, 1. Readiness; 2. Nimbleness, handiness, and handsomeness. The main strength of the body is in the loins. Therefore some say, the strong purposes and resolutions of the mind are here meant.
Hope to the end] Gr. τελειως, hope perfectly or entirely; q.d. do it not by halves; let there not be any odd reckonings between God and you, but work out your salvation,Philippians 2:12. See Trapp on " Php 2:12 "
For the grace] That is, for the glory.
That is to be brought unto you] It must be brought unto us (such is our dulness), we will scarcely go seek it, hardly be persuaded to live happily, reign everlastingly.
