St. John frequently mentions some great subject; at first like a musician who with perfect command of his instrument, touches what seems to be an almost random key, faintly, as if incidentally and half wandering from his theme. But just as the sound appears to be absorbed by the purpose of the composition, or all but lost in the distance, the same chord is struck again more decidedly; and then, after more or less interval, is brought out with a music so full and sonorous, that we perceive that it has been one of the master's leading ideas from the very first. So, when the subject is first spoken of, we hear--"every one that doeth righteousness is born of Him."[279] The subject is suspended for a while; then comes a somewhat more marked reference. "Whosoever is born of God is not a doer of sin; and he cannot continue sinning, because of God he is born." There is yet one more tender recurrence to the favourite theme--"every one that loveth is born of God."[280] Then, finally here at last the chord, so often struck, grown bolder since the prelude, gathers all the music round it. It interweaves with itself another strain which has similarly been gaining amplitude of volume in its course, until we have a great _Te Deum_, dominated by two chords of Birth and Victory. "This _is_ the conquest that has _conquered_ the world--the Faith which is of us." We shall never come to any adequate notion of St. John's conception of the Birth of God, without tracing the place in his Gospel to which his asterisk in this place refers. To one passage only can we turn--our Lord's conversation with Nicodemus. "Except a man be born again, he cannot see the kingdom of God--except a man be born of water and of the Spirit, he cannot enter into the kingdom of God."[281] The germ of the idea of entrance into the city, the kingdom of God, by means of a new birth, is in that storehouse of theological conceptions, the psalter. There is one psalm of a Korahite seer, enigmatical it may be, shadowed with the darkness of a divine compression,[282] obscure from the glory that rings it round, and from the gush of joy in its few and broken words. The 87th Psalm is the psalm of the font, the hymn of regeneration. The nations once of the world are mentioned among them that know the Lord. They are counted when He writeth up the peoples. Glorious things are spoken of the City of God. Three times over the burden of the song is the new birth by which the aliens were made free of Sion. This one was born there, This one and that one was born in her, This one was born there.[283]
