5 “He has chosen an inheritance for us, the excellency of Jacob, whom He loved”. A certain beauty of Jacob He has chosen for our inheritance. Esau and Jacob were two brothers; in their mother's womb both struggled, and by this struggle their mother's bowels were shaken; and while they two were yet therein, the younger was elected and preferred to the elder, and it was said, “Two peoples are in your womb, and the elder shall serve the younger.” Among all nations is the elder, among all nations the younger; but the younger is in good Christians, elect, godly, faithful; the elder in the proud, unworthy, sinful, stubborn, defending rather than confessing their sins: as was also the very people of the Jews, “being ignorant of God's righteousness, and going about to establish their own righteousness.” But for that it is said, “The elder shall serve the younger;” it is manifest that under the godly are subdued the ungodly, under the humble are subdued the proud. Esau was born first, and Jacob was born last; but he who was last born, was preferred to the first-born, who through gluttony lost his birthright. So you have it written, He longed for the pottage, and his brother said to him, If you will that I give it you, give me your birthright. He loved more that which carnally he desired, than that which spiritually by being born first he had earned: and he laid aside his birthright, that he might eat lentils. But lentils we find to be the food of the Egyptians, for there it abounds in Egypt. Whence is so magnified the lentil of Alexandria, that it comes even to our country, as if here grew no lentil. Therefore by desiring Egyptian food he lost his birthright. So also the people of the Jews, of whom it is said, “in their hearts they turned back again into Egypt.” They desired in a manner the lentil, and lost their birthright.
6. “God is gone up with jubilation”. Even He our God, the Lord Christ, is gone up with jubilation; “the Lord with the sound of a trumpet.” “Is gone up:” whither, save where we know? Whither the Jews followed Him not, even with their eyes. For exalted on the Cross they mocked Him, ascending into Heaven they did not see Him. “God has gone up with jubilation.” What is jubilation, but admiration of joy which cannot be expressed in words? As the disciples in joy admired, seeing Him go into Heaven, whom they had mourned dead; truly for the joy, words sufficed not: remained to jubilate what none could express. There was also the voice of the trumpet, the voice of Angels. For it is said, “Lift up your voice like a trumpet.” Angels preached the ascension of the Lord: they saw the Disciples, their Lord ascending, tarrying, admiring, confounded, nothing speaking, but in heart jubilant: and now was the sound of the trumpet in the clear voice of the Angels, “You men of Galilee, why stand ye gazing up into Heaven? This is Jesus.” As if they knew not that it was the same Jesus. Had they not just before seen Him before them? Had they not heard Him speaking with them? Nay, they not only saw the figure of Him present, but handled also His limbs. Of themselves then knew they not, that it was the same Jesus? But they being by very admiration, from joy of jubilation, as it were transported in mind, the Angels said, “that same is Jesus.” As though they said, If you believe Him, this is that same Jesus, whom crucified, your feet stumbled, whom dead and buried, you thought your hope lost. Lo, this is the same Jesus. He has gone up before you, “He shall so come in like manner as you have seen Him go into Heaven.” His Body is removed indeed from your eyes, but God is not separated from your hearts: see Him going up, believe in Him absent, hope for Him coming; but yet through His secret Mercy, feel Him present. For He who ascended into Heaven that He might be removed from your eyes, promised unto you, saying, “Lo, I am with you always, even unto the end of the world.” Justly then the Apostle so addressed us, “The Lord is at hand; be careful for nothing.” Christ sits above the Heavens; the Heavens are far off, He who there sits is near....
7. “Sing praises to our God, sing praises”. Whom as Man mocked they, who from God were alienated. “Sing praises to our God.” For He is not Man only, but God. Man of the seed of David, God the Lord of David, of the Jews having flesh. “Whose” (says the Apostle) “are the fathers, of whom as concerning the flesh Christ came.” Of the Jews then is Christ, but according to the flesh. But who is this Christ who is of the Jews according to the flesh? “Who is over all, God blessed for ever.” God before the flesh, God in the flesh, God with the flesh. Nor only God before the flesh, but God before the earth whence flesh was made; nor only God before the earth whereof flesh was made, but even God before the Heaven which was first made; God before the day which was first made; God before Angels; the same Christ is God: for “In the beginning was the Word, and the Word was with God, and the Word was God.”
8. “For God is the King of all the earth”. What? And before was He not God of all the earth? Is He not God of both heaven and earth, since by Him surely were all things made? Who can say that He is not his God? But not all men acknowledged Him their God; and where He was acknowledged, there only, so to say, He was God. “In Judah is God known.” Not yet was it said to the sons of Korah, “O clap your hands, all you nations.” For that God known in Judah, is King of all the earth: now by all He is acknowledged, for that is fulfilled which Isaiah says, “He is your God who has delivered you, the God of the whole earth shall He be called.” “Sing ye praises with understanding.” He teaches us and warns us to sing praises with understanding, not to seek the sound of the ear, but the light of the heart. The Gentiles, whence you were called that you might be Christians, adored gods made with hands, and sang praises to them, but not with understanding. If they had sung with understanding, they had not adored stones. When a man sensible sang to a stone insensible, did he sing with understanding? But now, brethren, we see not with our eyes Whom we adore, and yet correctly we adore. Much more is God commended to us, that with our eyes we see Him not. If with our eyes we saw Him, haply we might despise. For even Christ seen, the Jews despised; unseen, the Gentiles adored.
