For Christmas, I'm posting this excerpt from John Calvin…
And in the same region there were shepherds out in the field, keeping watch over their flock by night. And an angel of the Lord appeared to them, and the glory of the Lord shone around them, and they were filled with fear. And the angel said to them, “Fear not, for behold, I bring you good news of great joy that will be for all the people. For unto you is born this day in the city of David a Savior, who is Christ the Lord.
(Luke 2:8-11 ESV)
It would have been to no purpose that Christ was born in Bethlehem, if it had not been made known to the world. But the method of doing so, which is described by Luke, appears to the view of men very unsuitable. First, Christ is revealed but to a few witnesses, and that too amidst the darkness of night. Again, though God had, at his command, many honorable and distinguished witnesses, he passed by them, and chose shepherds, persons of humble rank, and of no account among men. Here the reason and wisdom of the flesh must prove to be foolishness; and we must acknowledge, that “the foolishness of God” (1 Corinthians 1:25) excels all the wisdom that exists, or appears to exist, in the world. But this too was a part of the “emptying of himself,” (Philippians 2:6:) not that any part of Christ’s glory should be taken away by it, but that it should lie in concealment for a time. Again, as Paul reminds us, that the gospel is mean according to the flesh, “that our faith should stand” in the power of the Spirit, not in the “lofty n words of human wisdom,” or in any worldly splendor, (1 Corinthians 2:4,5) so this inestimable “treasure” has been deposited by God, from the beginning, “in earthen vessels,” (2 Corinthians 4:7) that he might more fully try the obedience of our faith. If then we desire to come to Christ, let us not be ashamed to follow those whom the Lord, in order to cast down the pride of the world, has taken, from among the dung of cattle, to be our instructors.
