O to grace how great a debtor

Vintage Warfield:

The point of insistence in Calvinistic particularism is not that God saves out of the sinful mass of men only one here and there, a few brands snatched from the burning, but that God's method of saving men is to set upon them his almighty grace, to purchase them to himself by the precious blood of his Son, to visit them in the inmost core of their being by the creative operations of his Spirit, and himself, the Lord God Almighty, to save them.
