14:28-31 Christ raises the expectations of his disciples to something beyond what they thought was their greatest happiness. His time was now short, he therefore spake largely to them. When we come to be sick, and to die, we may not be capable of talking much to those about us; such good counsel as we have to give, let us give while in health. Observe the prospect Christ had of an approaching conflict, not only with men, but with the powers of darkness. Satan has something in us to perplex us with, for we have all sinned; but when he would disturb Christ, he found nothing sinful to help him. The best evidence of our love to the Father is, our doing as he has commanded us. Let us rejoice in the Saviour's victories over Satan the prince of this world. Let us copy the example of his love and obedience.
31. But that the world may know that I love the Father, &c.—The sense must be completed thus: "But to the Prince of the world, though he has nothing in Me, I shall yield Myself up even unto death, that the world may know that I love and obey the Father, whose commandment it is that I give My life a ransom for many."
Arise, let us go hence—Did they then, at this stage of the discourse, leave the supper room, as some able interpreters conclude? If so, we think our Evangelist would have mentioned it: see Joh 18:1, which seems clearly to intimate that they then only left the upper room. But what do the words mean if not this? We think it was the dictate of that saying of earlier date, "I have a baptism to be baptized with, and how am I straitened till it be accomplished!"—a spontaneous and irrepressible expression of the deep eagerness of His spirit to get into the conflict, and that if, as is likely, it was responded to somewhat too literally by the guests who hung on His lips, in the way of a movement to depart, a wave of His hand, would be enough to show that He had yet more to say ere they broke up; and that disciple, whose pen was dipped in a love to his Master which made their movements of small consequence save when essential to the illustration of His words, would record this little outburst of the Lamb hastening to the slaughter, in the very midst of His lofty discourse; while the effect of it, if any, upon His hearers, as of no consequence, would naturally enough be passed over.
