To this righteousness each "stranger and sojourner" in the world is striving to attain by faith, and by each exercise thereof he is raised nearer to his lofty aim. His faith, like the patriarch's of old, is counted unto him for righteousness. The fruit of each man's faith will be ἰσότιμος--"alike precious"--when the journey is ended. For it will be salvation in the presence of the perfect righteousness. As in the Saviour's parable the welcome was the same to him who had rightly used his two talents as to him who had done the like with five, so each faithful servant of Christ, working righteousness according to his power here, shall be called up into the joy of his Lord. For the joys of heaven all will not have the same capacity; but for each, according to his power to receive it, there will be fulness of joy. Nor should the word "obtained" pass unnoticed. It is the word used of Judas (Acts i. 17), who _obtained_ part of the apostolic ministry on the call of Jesus. So here, too, the call into the faith is of God; and it is when men obey it that they progress in Divine graces and go forward unto righteousness.
_Grace to you and peace be multiplied in the knowledge of God and of Jesus our Lord._ The first words are the same with the Apostle's prayer in the opening of the First Epistle. And to no stage of the Christian life can such a wish be inappropriate. To grow in grace, and so in peace, is the Christian's daily bread; and the thought of this seems to be uppermost in St. Peter's mind in this letter, that thus the falling away, to which he sees the converts are likely to be exposed, may be counteracted. The danger was arising from the boastful parade of a knowledge (γνῶσις) falsely so called (1 Tim. vi. 20). Before this letter was written teachers had risen within the Church who professed to have a deeper and more mysterious interpretation of the doctrines of the Gospel. This esoteric enlightenment they specially named "knowledge," and led men astray by profitless inquiries concerning the absolute nature of God and the manner of His communication with the world. To this teaching St. Paul is referring when he speaks of "foolish questions" and "endless genealogies," and it is this which St. Peter rebukes so vehemently in the next chapter of this letter. As an antidote for the poison, he urges the converts to seek after a true and full knowledge (ἐπίγνωσις) of the Father and the Son. No single word can adequately represent this term, which became the watchword of all the Christian teachers. It is that knowledge of the truth which St. Paul so often commends to Timothy (1 Tim. ii. 4; 2 Tim. iii. 7) and speaks of as that acknowledging of the truth, allowing it to be effective on the life, which follows repentance (2 Tim. ii. 25); it is specially the knowledge of God and of things Divine; it is that knowledge which must temper religious zeal (Rom. x. 2) that it may be effective; it is the knowledge against which if a man sin (Heb. x. 26) he is verily reprobate. And this true knowledge can only come of faithful service. He shall know the Lord who loves to do His will. Do the works, and ye shall know of the doctrine.
_Seeing that His Divine power hath granted unto us all things that pertain unto life and godliness._ The work, though great, becomes not impossible; the dangers and difficulties, though abundant, are not insurmountable. For it is not on us that the victory depends. God hath begotten us again unto a lively hope through Christ's resurrection; and Christ has promised to be with His servants all the days, even unto the end of the world. There is a free gift of Divine power for all our needs, everything to foster the spiritual life and to guide into the way of holiness. Wisdom will be given that we may understand God's will and choose aright, strength to persevere in the midst of trial, boldness to make confession of the Lord before men, and watchfulness lest we, as did the teachers of error, wax overconfident. All things are granted; all things may be ours.
