Matthew 22:14 seems clearly profession, or outward calling; the chosen, those owned in the wedding. As to Matthew 20 you must connect it with chapter 19. There devotedness and self-sacrifice are made the ground of reward. Only the principles of law and grace are so different, that those great in one would be very little in the other. But lest there should be self and self-righteousness wrought by what preceded, the sovereign grace of chapter 20 is introduced, and the converse stated— many last first, and first last. Here it is grace as to service: only so much work for so much pay is utterly blown upon. The rest trusted the master for what they might get, and free grace acts consequently. God alone can judge what He should do in rewarding. Thus last are first, and first last. Many are called to serve, some chosen vessels, but all is grace.
