2 Timothy 2:19

But the sure foundation of God and of the Christian faith standeth firm, though some fall from it, and will stand to the end of the world, the Church being built on a rock, and upon the promises of Christ, which cannot fail. Having this seal: the Lord knoweth who are his. The words are applied from Numbers xvi. 5. The sense is, that the faith and Church of Christ cannot fail, because God has decreed and promised to remain with his Church, and especially to protect his elect, to the end of the world. To know his, here is not only to have a knowledge, but is accompanied with a love and singular protection over them, with such graces as shall make them persevere to the end. --- And let every one that nameth (or invoketh) the name of the Lord, depart from iniquity. Several understand these words, which are similar to those Numbers xvi. 26. depart from the tents of these wicked men, to be as it were a second seal, or part of the seal of God's firm decree, inasmuch as the elect by his grace, or when they are prevented and assisted by his grace, will always depart from iniquity; will remain firm in faith, and in the practice of good works: so that this may rather be an effect of the former seal, i.e. of God's decree to protect his elect, than a different seal. (Witham) --- Whatever effects hell may make by its agents, the eternal edifice, of which the elect are living stones, is immoveable, being founded on the immutable decree of divine election, and upon the efficacious and infallible means, which separate the children of the wicked Adam, to bring them and to unite them to Jesus Christ.
