The reason for the holiness of Christians: v.20. Jesus verily was foreordained before the foundation of the world, but was manifest in these last times for you, v.21. who by Him do believe in God, that raised Him up from the dead, and gave Him glory, that your faith and hope might be in God.
How seriously God was concerned about the salvation of mankind is brought out in the next words: Who, indeed, was destined before the foundation of the world, but manifested at the end of the times for your sakes.
As the sacrificial Lamb, whose blood should serve for a ransom, as the Savior of the world, Christ was destined by God from eternity. Our salvation, the redemption through the blood of Christ, was not brought about by chance, is not due to some sudden caprice of God, but is based upon a counsel of love which was resolved upon by God before the beginning of time, before the foundations of this earth were laid, John 17, 24; Eph. 1, 4; Acts 2, 23.
And now the Son of God, the Savior of the world, was in these last times, at the beginning of the last world period, in the fullness of time, manifested. He who, as the eternal Son of God, had existed from eternity and had taken part in the counsel of God for the salvation of mankind, was made man for our sakes, in order to earn the redemption for us, in order to pay the price, or ransom, which was required in this unusual case.
This fact, that the blood of Christ, with its incomparable, priceless value, was paid as the price of our ransom from the power of sin and of Satan, that is the comfort of the Christians at all times, a comfort with which they may calmly defy the accusations of the devil and the terrors of the Judgment, and boldly look forward to the enjoyment of everlasting bliss before the throne of the Lamb.
The apostle not only applies the salvation of Christ to his readers in the words “for your sakes,” but also explains how this application takes place: Who through Him are believers in God, who raised Him from the dead and gave Him glory, in order that your faith and your hope be directed toward God.
Faith is not the result of a man’s own effort, of his own reason and sense. Through Christ, through His manifestation in the flesh, through His blood, through His redemption we have been placed into the right relation toward God, we have become believers, we have become sure of our sonship. Our faith thus rests in God, who, by raising Christ from the dead, has testified to the sufficiency of the ransom which was paid for our sins. Thus we rest our confidence in the reconciled Father, who has accepted and is accepting the intercessory prayer of Christ, our Advocate. Therefore our hope and our faith are directed toward God; we have the certain conviction that God will make us partakers of the glory of Christ.
