Nevertheless, the foundation of God standeth sure,.... That faith, which is the faith of God's elect, is of the operation of God, and is the gift of his grace, and of which Christ is the author and finisher, is firm and immovable as a foundation; it is solid and substantial; it is the substance of things hoped for; and it is permanent and abiding; it stands sure, being supported by the power of God, and prevalent mediation of Jesus Christ; and so cannot be overthrown by false teachers, when an historical faith, or the faith of temporary believers may: or the doctrine of the resurrection of the dead is here meant, which was said to be past by the above false teachers; which is a fundamental doctrine of the Gospel, without which the preaching of it is vain, and faith is vain; and which is a doctrine of God, of pure revelation; and this will be effected by his power: this stands sure upon the testimony of the patriarchs, prophets, and of Christ, and his apostles; upon the sure word and writings both of the Old and New Testament; and will stand its ground against all opposition, and will have its certain effect; for the Lord Jesus knows who are his distinctly and perfectly; nor will he lose them, nor anything that belongs to them; not their bodies, any more than their souls, nor any dust of theirs, but will raise it up at the last day.
Or else the doctrine of eternal election may be here designed; which is the foundation of all spiritual blessings, of faith and of holiness, of joy and comfort here, and happiness hereafter, and even of complete and everlasting salvation; and is of God's laying, and is owing to his sovereign pleasure and free rich grace; and stands sure, not on the foot of works, but upon the unchangeable and unfrustrable will of God; and this secures from a final and total deception by false teachers: and also into the account may be taken the persons of God's elect themselves; who are of God's founding, and are as immovable as the firmest foundation whatever, even as rocks and mountains, and stand sure upon the rock of ages, Christ Jesus, and shall never perish; nor can they be deceived by false Christs and false prophets, but will remain safe and sound, when the faith of ever so many is subverted by them.
Having this seal, the Lord knoweth them that are his: faith is sealed and insured to God's elect, by his foreknowledge and predestination of them; so that they certainly have it, and shall never lose it: and their election is according to God's foreknowledge of them; which designs not a foresight of their faith, holiness, and good works, as the motives of his choosing them; nor a bare prescience of their persons; but such a foreknowledge as includes special love to them, which is distinguishing, unchangeable, and everlasting; and this being a seal affixed to all the elect, shows the distinguishing grace of God in their election, the secrecy of it, and its firmness and irrevocableness, and also the safety of the chosen ones; things being sealed, to distinguish one thing from another, and to keep things secret, or to render them firm and authentic.
So, among the Jews, seals were used in buying and selling, that it might be known what was bought, and to confirm the purchase . The inference from this comfortable doctrine is,and let everyone that nameth the name of Christ; "or of the Lord", as the Alexandrian copy, and others, the Complutensian edition, the Vulgate Latin, Syriac, and Arabic versions read; that is, whoever either are called by the name of Christ, or Christians, or whoever call upon his name: let themdepart from iniquity; both from doctrinal iniquity, the errors and heresies of the above false teachers, which increased to ungodliness, and ate as a gangrene, and were the subversion of the faith of some; and from all practical iniquity, which those men, and their followers, especially the Gnostics, were guilty of; and, generally speaking, when men make shipwreck of faith, they put away a good conscience: and the apostle may also mean, that all such should depart from iniquitous men, from men whether of bad principles or practices, or both, and have no fellowship with them, it being unworthy of the name by which they were called.
Some reference seems to be had to Nu 16:5 and so the false teachers, and their followers, may be compared to Korah, and his company, and the elect of God to Moses, and the Lord's people, who were bid to depart from the tents of those wicked men; and who stood firm, sure, and safe, when the earth opened, and swallowed up the others.
