...the conversion of a sinner being not owing to a man's self determination, but to God's determination, and eternal election, which is absolute, and depending on the sovereign Will of God, and not on the free will of man; as is evident from what has been said : and it being very evident from the Scriptures, that the eternal election of saints to the faith and holiness, is also an election of them to eternal salvation; hence their appointment to salvation must also be absolute, and not depending on their contingent, self-determining will.

Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified. - Galatians 2:16
