John Gill emphasizes the importance of diligence in exercising the graces of faith and performing good works to ensure one's calling and election in Christ. He clarifies that this calling is an internal and effectual call to grace and glory, not merely an external or church-related call. Gill explains that while believers cannot make their election surer in God's eyes, they can demonstrate their calling to others through their actions and testimonies. He reassures that through diligence in these practices, believers can avoid falling into sin and maintain their spiritual integrity. Ultimately, the sermon encourages believers to actively live out their faith as evidence of their divine election.

Ver. 10. Wherefore the rather, brethren, give diligence,.... To exercise the afore mentioned graces, and to perform the above duties, since this is the way 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; instead of "calling", the Alexandrian copy reads, "comfort": and by "election" is meant, not a national, nor church election, but 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; see Ro 8:30 nor are those to be made sure by saints, with respect to themselves; for though they may sometimes be at a loss about them, and may have some scruples and doubts in their minds concerning their interest in them, and an assurance of their being both called and chosen, may be after all attained unto by them; 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, which they may do by giving them an account of the work of God upon their souls, joined with a testimony of their good lives and conversations; or rather to the world "by good works", as the Vulgate Latin version and two copies of Beza's read; or "by your good works", as the Alexandrian copy and the Syriac and Ethiopic versions read; or by the exercise of the graces, and the discharge of the duties before mentioned, whereby the men of the world may be certified and assured, by the best evidence the saints are capable of giving to them, or they of receiving, that they are the called and chosen of God, they profess themselves to be; and which is a reason why those things should be done: and another follows, 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. Another argument, strengthening the exhortation, follows:
