Monergism

The doctrine of election encounters strong opposition in the hearts of men, and it is therefore necessary to examine thoroughly its claim to our belief. As it relates to an act of the divine mind, no proof of its truth can be equal to the testimony of the Scriptures. Let us receive their teachings on the subject without hesitation or distrust; and let us require every preconceived opinion of ours, and all our carnal reasonings, to bow before the authority of God's holy word

From the views which have been presented, it necessarily follows, that election is not on the ground of foreseen faith or obedience. On this point, the teachings of Scripture are clear. They are chosen not because of their holiness, but that they may be holy; not because of their obedience, but unto obedience. As the discrimination made in effectual calling is God's work, and antecedent to all holiness, faith, or acceptable obedience; the purpose to discriminate could not be on the ground of acts foreseen, which do not exist as a consideration for the execution of the purpose. The discriminating grace which God bestows, is not on the ground of faith and obedience previously existing, bur for a reason known only to God himself. This unrevealed reason, and not foreseen faith and obedience, is the ground of election.
