Hebrews 6:3

will we do--So some of the oldest manuscripts read; but others, "Let us do." "This," that is, "Go on unto perfection." if God permit--For even in the case of good resolutions, we cannot carry them into effect, save through God "working in us both to will and to do of His good pleasure" (Phi 2:13). The "for" in Heb 6:4 refers to this: I say, if God permit, for there are cases where God does not permit, for example, "it is impossible," &c. Without God's blessing, the cultivation of the ground does not succeed (Heb 6:7).

In this chapter the apostle proceeds to persuade the Hebrews to make a better proficiency in religion than they had done, as the best way to prevent apostasy, the dreadful nature and consequences of which sin he sets forth in a serious manner (Heb 6:1-8), and then expresses his good hopes concerning them, that they would persevere in faith and holiness, to which he exhorts them, and sets before them the great encouragement they had from God, both with respect to their duty and happiness (Heb 6:9 to the end).

6:3 The author is implicitly exhorting his readers to maturity, not only in their understanding but in everything (cp. 4:11; 5:14; 10:23-39; 12:1-13).
