I composed the music to this song almost 40 years ago now. The lyrics are taken from “the last words of David,” the great Psalmist and King of Israel, found in II Samuel 23: 1-4.
As a young man, I was struck by the simple beauty of the words. It was many years later that I received a portion of their profound meaning. God said to David, “He that rules over men must be just, ruling in the fear of God.” And that ruler of men “shall be as the light of the morning.”
In other words, projecting on into the soon-coming Kingdom of Heaven age after Christ’s return to earth, His rulers will have His Spirit within them, as their guiding principle; they will be impartial, for God “rains on the just and the unjust.” They will not be respectors of persons, for they will be His children, made in His image.
And because they are the “children of light,” they will “let their light so shine on all men.” They will love all men, as the morning sun shines its rays on everyone on earth.
