2 Peter 1:5

Join with your faith, virtue: think not that faith alone will save you without the practice of virtues and good works. By abstinence or temperance, is understood that virtue which helps to moderate the inordinate love of sensual pleasures, and to govern all disorderly passions and affections. (Witham)

2. The apostle proposes two particular advantages that will attend or follow upon diligence in the work of a Christian: stability in grace, and a triumphant entrance into glory. These he brings in by resuming his former exhortation, and laying it down in other words; for what in v. 5 is expressed by giving diligence to add to faith virtue, etc., is expressed in v. 10 by giving diligence to make our calling and election sure. Here we may observe, (1.) It is the duty of believers to make their election sure, to clear it up to themselves that they are the chosen of God. (2.) The way to make sure their eternal election is to make out their effectual calling: none can look into the book of God's eternal counsels and decrees; but, inasmuch as whom God did predestinate those he also called, if we can find we are effectually called, we may conclude we are chosen to salvation. (3.) It requires a great deal of diligence and labour to make sure our calling and election; there must be a very close examination of ourselves, a very narrow search and strict enquiry, whether we are thoroughly converted, our minds enlightened, our wills renewed, and our whole souls changed as to the bent and inclination thereof; and to come to a fixed certainty in this requires the utmost diligence, and cannot be attained and kept without divine assistance, as we may learn from Ps 139 23; Rom 8 16. "But, how great soever the labour is, do not think much of it, for great is the advantage you gain by it; for," [1.] "By this you will be kept from falling, and that at all times and seasons, even in those hours of temptation that shall be on the earth." When others shall fall into heinous and scandalous sin, those who are thus diligent shall be enabled to walk circumspectly and keep on in the way of their duty; and, when many fall into errors, they shall be preserved sound in the faith, and stand perfect and complete in all the will of God. [2.] Those who are diligent in the work of religion shall have a triumphant entrance into glory; while of those few who get to heaven some are scarcely saved (1 Pet 4 18), with a great deal of difficulty, even as by fire (1 Cor 3 15), those who are growing in grace, and abounding in the work of the Lord, shall have an abundant entrance into the joy of their Lord, even that everlasting kingdom where Christ reigns, and they shall reign with him for ever and ever.

Verses 1-11 Faith unites the weak believer to Christ, as really as it does the strong one, and purifies the heart of one as truly as of another; and every sincere believer is by his faith justified in the sight of God. Faith worketh godliness, and produces effects which no other grace in the soul can do. In Christ all fulness dwells, and pardon, peace, grace, and knowledge, and new principles, are thus given through the Holy Spirit. The promises to those who are partakers of a Divine nature, will cause us to inquire whether we are really renewed in the spirit of our minds; let us turn all these promises into prayers for the transforming and purifying grace of the Holy Spirit. The believer must add knowledge to his virtue, increasing acquaintance with the whole truth and will of God. We must add temperance to knowledge; moderation about worldly things; and add to temperance, patience, or cheerful submission to the will of God. Tribulation worketh patience, whereby we bear all calamities and crosses with silence and submission. To patience we must add godliness: this includes the holy affections and dispositions found in the true worshipper of God; with tender affection to all fellow Christians, who are children of the same Father, servants of the same Master, members of the same family, travellers to the same country, heirs of the same inheritance. Wherefore let Christians labour to attain assurance of their calling, and of their election, by believing and well-doing; and thus carefully to endeavour, is a firm argument of the grace and mercy of God, upholding them so that they shall not utterly fall. Those who are diligent in the work of religion, shall have a triumphant entrance into that everlasting kingdom where Christ reigns, and they shall reign with him for ever…
