Verse 18. But grow in grace. Comp. Col 1:10. Religion in general is often represented as grace, since every part of it is the result of grace, or of unmerited favour; and to "grow in grace" is to increase in that which constitutes true religion. Religion is as susceptible of cultivation and of growth as any other virtue of the soul. It is feeble in its beginnings, like the grain of mustard seed, or like the germ or blade of the plant, and it increases as it is cultivated. There is no piety in the world which is not the result of cultivation, and which cannot be measured by the degree of care and attention bestowed upon it. No one becomes eminently pious, any more than one becomes eminently learned or rich, who does not intend to; and ordinarily men in religion are what they design to be. They have about as much religion as they wish, and possess about the character which they intend to possess. When men reach extraordinary elevations in religion, like Baxter, Payson, and Edwards, they have gained only what they meant to gain; and the gay and worldly professors of religion, who have little comfort and peace, have in fact the characters which they designed to have. If these things are so, then we may see the propriety of the injunction "to grow in grace;" and then too we may see the reason why so feeble attainments are made in piety by the great mass of those who profess religion.

And in the knowledge of our Lord and Saviour Jesus Christ. Jn 17:3. Comp. Col 1:10. To know the Lord Jesus Christ--to possess just views of his person, character, and work---is the sum and essence of the Christian religion; and with this injunction, therefore, the apostle appropriately closes this epistle. He who has a saving knowledge of Christ, has in fact all that is essential to his welfare in the life that is, and in that which is to come; he who has not this knowledge, though he may be distinguished in the learning of the schools, and may be profoundly skilled in the sciences, has in reality no knowledge that will avail him in the great matters pertaining to his eternal welfare.

To him be glory, etc. Comp. Rom 16:27; 2Ti 4:18. With the desire that honour and glory should be rendered to the Redeemer, all the aspirations of true Christians appropriately close. There is no wish more deeply cherished in their hearts than this; there is nothing that will enter more into their worship in heaven; Compare Rev 1:5,6, 5:12,13.

Verse 18 But grow in grace - Increase in the image and favor of God; every grace and Divine influence which ye have received is a seed, a heavenly seed, which, if it be watered with the dew of heaven from above, will endlessly increase and multiply itself. He who continues to believe, love, and obey, will grow in grace, and continually increase in the knowledge of Jesus Christ, as his sacrifice, sanctifier, counsellor, preserver, and final Savior. The life of a Christian is a growth; he is at first born of God, and is a little child; becomes a young man, and a father in Christ. Every father was once an infant; and had he not grown, he would have never been a man. Those who content themselves with the grace they received when converted to God, are, at best, in a continual state of infancy: but we find, in the order of nature, that the infant that does not grow, and grow daily, too, is sickly and soon dies; so, in the order of grace, those who do not grow up into Jesus Christ are sickly, and will soon die, die to all sense and influence of heavenly things. There are many who boast of the grace of their conversion; persons who were never more than babes, and have long since lost even that grace, because they did not grow in it. Let him that readeth understand. To him - The Lord Jesus, be glory - all honor and excellency attributed, both now - in this present state, and for ever, εις ἡμεραν αιωνος, to the day of eternity - that in which death, and misery, and trial, and darkness, and change, and time itself, are to the righteous for ever at an end: it is eternity; and this eternity is one unalterable, interminable, unclouded, and unchangeable Day! Amen - So let it be! and so it shall be! Though this word is wanting in some reputable MSS., get it should be retained, as it has here more than usual authority in its support.

We have now passed over all the canonical writings of Peter that are extant; and it is worthy of remark that, in no place of the two epistles already examined, nor in any of this apostle's sayings in any other parts of the sacred writings do we find any of the peculiar tenets of the Romish Church: not one word of his or the pope's supremacy; not one word of those who affect to be his successors; nothing of the infallibility claimed by those pretended successors; nothing of purgatory, penances, pilgrimages, auricular confession, power of the keys, indulgences, extreme unction, masses, and prayers for the dead; and not one word on the most essential doctrine of the Romish Church, transubstantiation. Now, as all these things have been considered by themselves most essential to the being of that Church; is it not strange that he, from whom they profess to derive all their power, authority, and influence, in spiritual and secular matters, should have said nothing of these most necessary things? Is it not a proof that they are all false and forged; that the holy apostle knew nothing of them; that they are no part of the doctrine of God; and, although they distinguish the Church of Rome, do not belong to the Church of Christ? It is no wonder that the rulers of this Church endeavor to keep the Scriptures from the common people; for, were they permitted to consult these, the imposture would be detected, and the solemn, destructive cheat at once exposed.
