"Those, then, who make the sacrifice, will have the testimony that their course is pleasing in the sight of God; and those who have this testimony will have faith to lay hold on eternal life, and will be enabled, through faith, to endure unto the end, and receive the crown that is laid up for them that love the appearing of our Lord Jesus Christ. But those who do not make the sacrifice cannot enjoy this faith, because men are dependent upon this sacrifice in order to obtain this faith; therefore they cannot lay hold upon eternal life, because the revelations of God do not guarantee unto them the authority so to do, and without this guarantee faith could not exist." "All the saints of whom we have any account, in all the revelations of God which are extant, obtained the knowledge which they had of their acceptance in his sight through the sacrifice which they offered unto him; and through the knowledge thus obtained their faith became sufficiently strong to lay hold upon the promise of eternal life, and to endure as seeing him who is invisible; and were enabled, through faith, to combat the powers of darkness, contend against the wiles of the adversary, overcome the world, and obtain the end of their faith, even the salvation of their souls."[E] [Footnote E: Doc. and Cov., Lecture on Faith, No. VI.] This, then, is my exposition of the grand principle of faith: It is an assurance of the mind of the existence or reality of things not seen, or that have not been demonstrated to any other of the senses. It takes root in evidence, more or less convincing to the understanding; and the strength of the faith depends largely upon the quality and quantity of the evidence. The more unquestionable, the more overwhelming the evidence, the more strong and immovable will be the faith.
