2 Timothy 2:19

Nevertheless the foundation of God standeth sure; notwithstanding that these two men (possibly of some note in the church of Ephesus) have fallen from the faith, and have been ill instruments to subvert the faith of others, yet God hath a number in the world, who are built upon the rock Christ Jesus, Matthew 7:25; these are founded surely, having this seal, The Lord knoweth them that are his; sealed, and confirmed in their state by the eternal decree and counsel of God, who hath foreknown his elect, both as to their number and perseverance; but God hath from eternity known who are his, and therefore such as truly are so must be kept through faith by his power to salvation, and it is not possible that these should be totally and finally deceived. And, Let every one that nameth the name of Christ depart from iniquity; and every one that nameth the name of the Lord must depart from the tents of wicked men, who have made shipwreck both of faith and a good conscience. Therefore let not the apostacy of these men be a temptation to thee to think that the church of God may or shall fail; that cannot be, there can be no more lost than the sons of perdition, such as God never knew as his, though they put on a mark of Christianity and godliness, and deceived many. Those who have God's seal upon them, and are of his foundation, shall stand and keep themselves from those damnable errors. Only, to let us know that neither the certainty of God's decree or promise doth excuse our endeavours and using means for obtaining the thing decreed or promised, the apostle puts the verb in the imperative mood: Let him depart, &c.
