1 Corinthians 15:1-2, 58

Friends, let me go over the Message with you one final time—this Message that I proclaimed and that you made your own; this Message on which you took your stand and by which your life has been saved. (I’m assuming, now, that your belief was the real thing and not a passing fancy, that you’re in this for good and holding fast.)

With all this going for us, my dear, dear friends, stand your ground. And don’t hold back. Throw yourselves into the work of the Master, confident that nothing you do for him is a waste of time or effort.
