2:14-21 Those disposed to strive, commonly strive about matters of small moment. But strifes of words destroy the things of God. The apostle mentions some who erred. They did not deny the resurrection, but they corrupted that true doctrine. Yet nothing can be so foolish or erroneous, but it will overturn the temporary faith of some professors. This foundation has two writings on it. One speaks our comfort. None can overthrow the faith of any whom God hath chosen. The other speaks our duty. Those who would have the comfort of the privilege, must make conscience of the duty Christ gave himself for us, that he might redeem us from all iniquity, Tit 2:14. The church of Christ is like a dwelling: some furniture is of great value; some of smaller value, and put to meaner uses. Some professors of religion are like vessels of wood and earth. When the vessels of dishonour are cast out to be destroyed, the others will be filled with all the fulness of God. We must see to it that we are holy vessels. Every one in the church whom God approves, will be devoted to his Master's service, and thus fitted for his use.

19. Nevertheless—Notwithstanding the subversion of their faith, "the firm foundation of God standeth" fast (so the Greek ought to be translated). The "foundation" here is "the Church" [Alford], "the ground" or basement support "of the truth" (1Ti 3:15), Christ Himself being the ultimate "foundation" (1Co 3:11). In the steadfast standing of the Church there is involved the steadfast certainty of the doctrine in question (2Ti 2:18). Thus the "house" (2Ti 2:20) answers to the "foundation"; it is made up of the elect whom "the Lord knoweth" (acknowledgeth, recognizes, Ps 1:6; Mt 7:23; Joh 10:14; 1Co 8:3) as "His," and who persevere to the end, though others "err concerning the faith" (Mt 24:24; Joh 10:28; Ro 8:38, 39; 1Jo 2:19). Bengel takes "the foundation" to be the immovable faithfulness of God (to His promises to His elect [Calvin]). This contrasts well with the erring from the faith on the part of the reprobate, 2Ti 2:18. Though they deny the faith, God abates not His faithfulness (compare 2Ti 2:13).

having—seeing that it has [Ellicott].

seal—"inscription": indicating ownership and destination: inscriptions were often engraven on a "foundation" stone (Re 21:14) [Alford]. This will agree with the view that "the foundation" is the Church (Eph 2:20). If it be taken God's immovable faithfulness, the "seal" will be regarded as attached to His covenant promise, with the inscription or legend, on one side of its round surface, "The Lord knoweth (it is 'knew' in the Septuagint, Nu 16:5, to which Paul here alludes, altering it for his purpose by the Spirit) them that are His"; on the observe side, "Let every one that nameth (as his Lord, Ps 20:7, or preacheth in His name, Jer 20:9) Christ."

depart—Greek, "stand aloof."

from iniquity—(Isa 52:11). In both clauses there may be an allusion to Nu 16:5, 26, Septuagint. God's part and man's part are marked out. God chooseth and knoweth His elect; our part is to believe, and by the Spirit depart from all iniquity, an unequivocal proof of our being the Lord's (compare De 29:29; Lu 13:23-27). St. Lucian when asked by his persecutors, "Of what country art thou?" replied, "I am a Christian." "What is your occupation? … I am a Christian." "Of what family? … I am a Christian." [Chrysostom, Orations, 75]. He cannot be honored with the name Christian, who dishonors by iniquity, Christ, the Author of the name. Blandina's refreshment amidst her tortures was to say, "I am a Christian, and with us Christians no evil is done" [Eusebius, Ecclesiastical History, 5.1]. Apostasy from the faith is sure soon to be followed by indulgence in iniquity. It was so with the false teachers (2Ti 3:2-8, 13).
