Samuel Rutherford (Letters, pp. 600-601):
nbelief is a spiritual sin, and so not seen by nature’s light; and that all which conscience saith is not Scripture. Suppose that your heart bear witness against you for sins done long ago: yet, because many have pardon with God that have not peace with themselves, ye are to stand and fall by Christ’s esteem and verdict of you, and not by that which your heart saith. Suppose it may, by accident, be a good sign to be jealous of your heavenly Husband’s love, yet it is a sinful sign; as there be some happy sins (if I may speak so), not of themselves, but because they are neighboured with faith and love. And so . . . I would have you to hold by this, that the ancient love of an old husband standeth firm and sure. And let faith hing by this small thread, that He loved you before He laid the corner-stone of the world, and therefore He cannot change His mind; because He is God, and resteth in His love. Neither is sin in you a good reason wherefore ye should doubt of Him, or think, because sin hath put you in the courtesy and reverence of justice, that therefore He is wroth with you: neither is it presumption in you to lay the burden of your salvation on One mighty to save, so being that ye lay aside all confidence in yourself, your worth and righteousness. True faith is humble, and seeth no way to escape but only in Christ. And I believe that ye have put an esteem and high price upon Christ: and they cannot but believe, and so be saved, who love Christ, and to whom He is precious; for the love of Christ has chosen Christ as a lover. And it were not like God, if ye should choose Him as your liking, and He not choose you again. Nay, He hath prevented you in that, for ye have not chosen Him, but He hath chosen you.
