It is true that God, before the foundation of the world, fully determined with Himself whom to choose to salvation by grace, to which also He ordained them, and whom to pass by and leave in their sins, for which He determined in His just wrath to condemn them. But who these be is a secret which even the elect themselves cannot know until they be effectually called—nay, nor being called, until by some experience and proofs of their faith and holiness, they do understand the witness of the Spirit, which testifies to their spirits that they are the children of God and do make their calling and election, which was always sure in God, sure to themselves.
