A Saving Faith...

"Much more than being a mode of knowledge, faith involves a sincere trust in Christ and his gospel for salvation. 

"Question and Answer 86 of the Westminster Shorter Catechism provides a concise and helpful statement of this insight. In response to the question of what faith in Jesus Christ is, the catechism answers: "Faith in Jesus Christ is a saving grace, whereby we receive and rest upon him alone for salvation, as he is offered to us in the gospel." Not only must the mind grasp the things about Christ and his gospel, but also the heart must rest upon him as the perfect Savior from sins. This character of justifying faith as trust in Christ has prompted some theologians to speak of faith as "extraspective." The term introspective is familiar to most people: it refers to looking within oneself. Something that is extraspective, then, concerns looking outside oneself. That is precisely what faith as trust does: it looks outside of oneself (thereby forsaking all self-confidence) and rests upon another, the Lord Jesus Christ, who has done all things necessary for our salvation."
