"He that submits his understanding to all that he knows God hath said, and is ready to submit to all that he hath said if he but know it, denying his own affections and ends, and interests and humane persuasions, laying them all down at the foot of his great Master Jesus Christ, that man hath brought his understanding into subjection, and every proud thought unto the obedience of Christ, and this is εἰς ὑπακοὴν πίστεως, the obedience of Faith, which is the duty of a Christian."
