The angels sang something which men could understand—something which men ought to understand—something which will make men much better if they will understand it. The angels were singing about Jesus who was born in the manger. We must look upon their song as being built upon this foundation. They sang of Christ, and the salvation which he came into this world to work out. And what they said of this salvation was this: they said, first, that it gave glory to God; secondly, that it gave peace to man; and, thirdly, that it was a token of God's good will towards the human race.
