Link to Luther's Jubilate Sermon
7. The first "a little while" in that he says, "A little while, and ye shall behold me no more," they could soon afterwards understand, when they saw that he was taken prisoner and put to death, but the second "a little while" in that he says: "And again a little while, and ye shall see me," that they could not understand, and we also cannot understand it. Yea and when he says: "Because I go to the Father," that they understand still less. Thus it also goes with us: although we know and hear that trials, misfortune and sorrow endure but a little while, yet we see that it constantly appears different than we believe. Then we despair and waver, and cannot be reconciled to it. We hear and we know very well that it shall not last very long, but how that result shall be accomplished we can never understand, as the disciples here cannot understand it.
8. But since they are unable to understand it why does Christ relate it to them or why is it written? In order that we should not despair but hold fast to the Word, assured that it is indeed thus and not otherwise, even though it seems to be different. And although we do at times depart from the Word, we should not therefore remain altogether away from it, but return again, for he makes good his Word. Even though man cannot believe it, God will nevertheless help him to believe it, and this he does without man's reason or free will and without man adding anything thereto. Yea, the Evangelist tells us that the disciples could not understand the words the Lord spake to them; how much less could they understand his works which followed afterwards. So very little does the free will and understanding of man know of the things pertaining to the salvation of the soul. These temporal things the free will can perceive and know, such as the cock crowing, which he can hear and his reason can also understand it; but when it is a question of understanding the work and Word of God, then human reason must give it up; it cannot make head or tail of it, although it pretends to understand a great deal about it. The glory thereof is too bright, the longer he beholds it the blinder he becomes.
