Jonathan Edwards believed that, while justification was through faith alone, a necessary fruit of faith was holiness, and therefore “the compliance of the whole soul with God’s authority and his holy nature and will in all things is implied in the very nature, spirit and act of true justifying faith.” He continues,
It will appear to be thus whether we consider justifying faith as a receiving Christ in all his offices–and so in the office of a king–or only a cordial receiving him in the office of his priesthood and as our atonement and righteousness. A hearty receiving Christ thus does directly imply a consenting to, complying with and embracing God’s holy nature, authority and will, and that a great many ways.*
Later, Edwards adds, “Though the receiving and submitting to Christ in his kingly office directly as such, or as this has a direct respect to the kingly office, is not that which justifies; yet this, as ’tis the proper exercise and expression of trusting in Christ for the benefits of his priesthood, does properly belong to that faith which is the most proper condition or qualification for justification.”**
