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.

So the parable of the sweep-net (Mt 13:47-49) gathering together of every kind, good and bad: as the good and bad cannot be distinguished while under the waves, but only when brought to shore, so believers and unbelievers continue in the same Church, until the judgment makes the everlasting distinction. "The ark of Noah is a type of the Church; as in the former there were together the leopard and the kid, the wolf and the lamb; so in the latter, the righteous and sinners, vessels of gold and silver, with vessels of wood and earth" [Jerome, Dialogue against the Luciferians, 302] (compare Mt 20:16).

vessels of gold … silver—precious and able to endure fire.

of wood and earth—worthless, fragile, and soon burnt (1Co 3:12-15; 15:47).

some … some—the former … the latter.

to dishonour—(Pr 16:4; Ro 9:17-23).
