2-е Петра 1:8

be--Greek, "subsist" that is, supposing these things to have an actual subsistence in you; "be" would express the mere matter-of-fact being (Act 16:20). abound--more than in others; so the Greek. make--"render," "constitute you," habitually, by the very fact of possessing these graces. barren--"inactive," and, as a field lying fallow and unworked (Greek), so barren and useless. unfruitful in--rather, . . . in respect to, "The full knowledge (Greek) of Christ" is the goal towards which all these graces tend. As their subsisting in us constitutes us not barren or idle, so their abounding in us constitutes us not unfruitful in respect to it. It is through doing His will, and so becoming like Him, that we grow in knowing Him (Joh 7:17).

In this chapter we have, I. An introduction, or preface, making way for, and leading to, what is principally designed by the apostle (Pe2 1:1-4). II. An exhortation to advance and improve in all Christian graces (Pe2 1:5-7). III. To enforce this exhortation, and engage them seriously and heartily to comply with it, he adds, 1. A representation of the very great advantage which will thereby accrue to them (Pe2 1:8-11). 2. A promise of the best assistance the apostle was able to give to facilitate and forward this good work (Pe2 1:12-15). 3. A declaration of the certain truth and divine origin of the gospel of Christ, in the grace whereof they were exhorted to increase and persevere.
