Faith, in Christian theology, usually means the assent of the soul to the promises of God and the revelation of His will coupled with the confidence that He will perform His promises. The term thus expresses both acceptance of a system of doctrine and confidence in a Person; and besides intellectual assent, it involves a special state of the emotions and direction of the will. As assent to a system of doctrine, it is often contrasted with reason. Reason draws a conclusion from premises, faith (it is said) deals with and accepts a conclusion which is beyond the reach of unaided human reason, but certified by a kind of inward revelation.
