2 Peter 1:10

He mentions calling first, though the last in order. The reason is, because election is of greater weight or importance; and it is a right arrangement of a sentence to subjoin what preponderates. The meaning then is, labor that you may have it really proved that you have not been called nor elected in vain. At the same time he speaks here of calling as the effect and evidence of election. If any one prefers to regard the two words as meaning the same thing, I do not object; for the Scripture sometimes merges the difference which exists between two terms. I have, however, stated what seems to me more probable.

Now a question arises, Whether the stability of our calling and election depends on good works, for if it be so, it follows that it depends on us. But the whole Scripture teaches us, first, that God's election is founded on his eternal purpose; and secondly, that calling begins and is completed through his gratuitous goodness. The Sophists, in order to transfer what is peculiar to God's grace to ourselves, usually pervert this evidence. But their evasions may be easily refuted. For if any one thinks that calling is rendered sure by men, there is nothing absurd in that; we may however, go still farther, that every one confirms his calling by leading a holy and pious life. But it is very foolish to infer from this what the Sophists contend for; for this is a proof not taken from the cause, but on the contrary from the sign or the effect. Moreover, this does not prevent election from being gratuitous, nor does it shew that it is in our own hand or power to confirm election. For the matter stands thus, — God effectually calls whom he has preordained to life in his secret counsel before the foundation of the world; and he also carries on the perpetual course of calling through grace alone. But as he has chosen us, and calls us for this end, that we may be pure and spotless in his presence; purity of life is not improperly called the evidence and proof of election, by which the faithful may not only testify to others that they are the children of God, but also confirm themselves in this confidence, in such a manner, however, that they fix their solid foundation on something else.

At the same time, this certainty, mentioned by Peter, ought, I think, to be referred to the conscience, as though the faithful acknowledged themselves before God to be chosen and called. But I take it simply of the fact itself, that calling appears as confirmed by this very holiness of life. It may, indeed, be rendered, Labor that your calling may become certain; for the verb ποιεῖσθαι is transitive or intransitive. Still, however you may render it, the meaning is nearly the same.

The import of what is said is, that the children of God are distinguished from the reprobate by this mark, that they live a godly and a holy life, because this is the design and end of election. Hence it is evident how wickedly some vile unprincipled men prattle, when they seek to make gratuitous election an excuse for all licentiousness; as though, forsooth! we may sin with impunity, because we have been predestinated to righteousness and holiness!

For if ye do these things. Peter seems again to ascribe to the merits of works, that God furthers our salvation, and also that we continually persevere in his grace. But the explanation is obvious; for his purpose was only to shew that hypocrites have in them nothing real or solid, and that, on the contrary, they who prove their calling sure by good works, are free from the danger of falling, because sure and sufficient is the grace of God by which they are supported. Thus the certainty of our salvation by no means depends on us, as doubtless the cause of it is beyond our limits. But with regard to those who feel in themselves the efficacious working of the Spirit, Peter bids them to take courage as to the future, because the Lord has laid in them the solid foundation of a true and sure calling.
