The sacrifice of all things

Let us here observe that a religion that does not require the sacrifice of all things never has power sufficient to produce the faith necessary unto life and salvation...When a man has offered in sacrifice all that he has for the truth's sake, not even withholding his life, and believing before God that he has been called to make this sacrifice because he seeks to do his will, he does know, most assuredly, that God does and will accept his sacrifice and offering and that he has not, nor will not, seek His face in vain.  Under these circumstances, then, he can obtain the faith necessary for him to lay hold on eternal life.  It is in vain for persons to fancy to themselves that they are heirs with those, or can be heirs with them, who have offered their all in sacrifice, and by this means obtain faith in God and favor with Him so as to obtain eternal life, unless they, in like manner, offer unto Him the same sacrifice, and through that offering obtain the knowledge that they are accepted of Him.
