In the section called Of God’s Eternal Decree (3.7), the Westminster Confession of Faith cites 2 Timothy 2:19-20 as a proof-text:
“Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, Let every one that nameth the name of Christ depart from iniquity. But in a great house there are not only vessels of gold and of silver, but also of wood and of earth; and some to honour, and some to dishonour.”
The reprobates are those whom God has unconditionally determined to damn before the creation of the world. These vessels of dishonor do not ultimately choose for themselves what kind of vessel they will be; rather, by their reaction to the work of Jesus Christ as making the difference between salvation and damnation by demanding and ensuring the salvation of all whom He represented, it is revealed what kind of vessel God has chosen them to be.
An unwavering and steadfast adherence to the biblical doctrine of unconditional reprobation — which necessarily includes active hardening — is not some sort of twisted fascination. On the contrary, this doctrine preserves and protects the purity of the gospel of salvation conditioned on the atoning blood and imputed righteousness of Christ alone.
The framers of the WCF, under a pseudo-pious pretense of protecting God’s holiness, have undermined and blasphemed His absolute sovereignty. For they have imposed their own man-made standard of righteousness upon Almighty God, to which He must conform in order for Him to remain righteous in their self-exalting eyes. They invent absurd and blasphemous fictions in order to retain a false sense of control (cf. Psalm 2:3; Psalm 12:4).
If you do not believe in the God who controls all actions and events, you do not believe the promise-keeping God of the Bible. You do not believe the gospel of salvation conditioned on the atoning blood and imputed righteousness of Jesus Christ alone. Bow to the Almighty Sovereign God, the Creator and Controller of the Universe.
