In this daily enlightenment must God's faithful ones live, a life whose atmosphere is the hallowing influence of the Holy Ghost. But it is to be no mere life of receptivity, with no effort of their own. The Apostle makes this clear elsewhere, when he says, "Sanctify the Lord God in your hearts" (iii. 15)--make them fit abodes for His Spirit to dwell in; lead your lives in holy conversation, that the house may be swept and garnished, and you be vessels sanctified and meet for the Master's use.
Thus chosen by the Father and led onward by the Spirit, the Christian is brought ever nearer to the full purpose of his calling: _unto obedience and the sprinkling of the blood of Jesus Christ_. The Christ-pattern which the Spirit sets before men is in no feature more striking than in its perfect obedience. The prophetic announcement of this submission sounds down to us from the Psalms: "Lo, I come to do Thy will, O God"; and the incarnate Son declares of Himself, "My meat is to do the will of Him that sent Me, and to finish His work": and even in the hour of His supreme agony His word is still, "Father, not My will, but Thine, be done." Specially solemn, almost startling, is the language of the Apostle to the Hebrews when he says of Jesus that "He learned obedience by the things which He suffered," and that "it became the Father, in bringing many sons unto glory, to make Christ, the Captain of their salvation, perfect through suffering." With the Lord as an example, obedience is made the noblest, the New Testament form of sacrifice.
But when such obedience was connected with the sprinkling of the blood of Jesus, the Jews among St. Peter's converts must have been carried in thought to that scene described in Exod. xxiv. There, through Moses as a mediator, we read of God's law being made known to Israel, and the people with one voice promised obedience: "All the words which the Lord hath said will we do, and be obedient." Then followed a sacrifice; and Moses took the blood and sprinkled it on the people, saying, "Behold the blood of the covenant which the Lord hath made with you concerning all these words"; and the Lord drew nigh unto His people, and the sight of the glory of the Lord on Mount Sinai was like devouring fire in the eyes of the children of Israel.
For Christians there is a Mediator of a better covenant. We are not come unto the mount that burned with fire, but unto Mount Zion (Heb. xii. 18-22). In that other sacrament of His own institution, our Lord makes us partakers of the benefits of His passion. With His own blood He constantly maketh His people pure, fitting them to appear in the presence of the Father. There at length the purpose of their election shall be complete in fulness of joy in the sight of Him who chose them before the foundation of the world.
Thus does the Apostle set forth his practical, profitable lessons on the work of the Trinity in man's election and salvation; and he concludes them with a benediction part of which is very frequent in the letters of St. Paul: _Grace to you and peace_. The early preachers felt that these two blessings travelled hand in hand, and comprised everything which a believer could need: God's favour and the happiness which is its fruit. Grace is the nurture of the Christian life; peace is its character. These strangers of the dispersion had been made partakers of the Divine grace. This very letter was one gift more, the consolation of which we can well conceive. But St. Peter models his benediction to be a fitting sequel to his previous teaching. _Grace_, he says, _to you and peace be multiplied_. The verb "be multiplied" is only used by him here and in the Second Epistle, and by St. Jude, whose letter has so much in common with St. Peter's.
