Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will, To the praise of the glory of his grace, wherein he hath made us accepted in the beloved. In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace" -- Ephesians 1:4-7"According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:
I have no interest in any aspect of Calvin’s teachings based on his perversion of Scripture and the writings of St. Augustine. God is not the weak monster god of Calvin.
