2 Peter 1:10 Wherefore the rather, brethren, give diligence[1]
To make your calling and election sure
By calling is not meant a call to any office in the church, nor an external call, either by the voice of nature, or by the ministry of the word; but an internal and effectual call by special grace, to grace here, and glory hereafter; [a] “calling”. . . [of] a particular and personal one, since scattered saints, and particular believers, are here written to, and each called upon to be diligent to make their own, and not another's, calling and election sure; nor is a choice of persons to an office designed, seeing the apostle writes not to officers of churches in particular, but to believers in common; nor a separation of persons from the world by the effectual calling, since these two are both mentioned here, and as distinct from each other, and to be made sure; but an election of particular persons to eternal life and salvation is here intended, which is an eternal act of God, arises from his free grace and favour, and is according to his sovereign will and pleasure; and is absolute, and independent of any condition, foreseen, or required in men, as faith, holiness, and good works; all which are fruits and effects, and not causes and conditions of electing grace. These may be made “sure” not in themselves, or with respect to God, for in this sense they cannot be made surer than they are: effectual calling is according to the purpose of God, which cannot be frustrated, and is, without repentance, irreversible, and irrevocable, and is inseparably connected with eternal glory; and election stands not upon the foot of works, but upon the free grace of God, which cannot be made void, and upon the will of God, which cannot be resisted; and is also closely connected with glorification; . . . yet this is not their work, but it is the work of the Spirit of God, to certify and make sure unto them, or assure them of their calling and election of God: but the sense is, that diligence is to be used by the saints, to make their calling and election sure to others; not their election by their calling only, which is to themselves; for both are to be made sure, and that to others, and by some third thing; either to their fellow Christians. . . .
For if ye do these things, ye shall never fall
Or “sin” as the Vulgate Latin and Arabic versions render it; not that they should never fall at all, or in any sense, for in many things we all offend or fall; or should ever commit any act of sin, or fall into sin, for there is no man that lives, and sins not; or that they should not fall from a degree of the lively exercise of grace, or from a degree of steadfastness in the doctrine of faith, but that they should never sin the sin against the Holy Ghost, or fall totally and finally; for though they fall, they should rise again by faith and repentance, through the grace and power of Christ, who is able to keep them from falling: and besides, while they were exercising those graces, and doing those duties, they should not fall; for these are the means of final perseverance, and therefore the rather to be regarded.
