Of the election of believers the Apostle here speaks in its origin, its progress, and its consummation. He views it as a process which must extend through the whole life, and connects its various stages with the Three Persons of the Trinity. But, with the same practical instinct which has already been noticed, he enters on no statements about the nature of the Godhead in itself; he neither discusses what may be known of God, nor how the knowledge is to be obtained. He says no word to intimate that the mention of three Persons may be difficult to understand in co-relation to the unity of the Godhead. Such inquiries exercise the mind, but can hardly further, what was St. Peter's special aim, the edification and comfort of the soul. That result comes from the inward experience of what each Person of the Godhead is to us, and on this the Apostle has a lesson. He makes plain for us the share which Father, Son, and Spirit bear in the work of human salvation. Christians, he teaches us, are elect, chosen to be saints, according to the foreknowledge of God the Father; the election is maintained when their lives are constantly hallowed by the influence of the Holy Ghost; while in Christ they have not only an example of perfect obedience after which they must strive, but a Redeemer whose blood can cleanse them from all the sins from which the most earnest strivings will not set them free. Of these things the Christian soul can have experience. It is thus that the life of the elect believer begins, grows, and is perfected.
