It is akin to the credit on which commerce is conducted, the goodwill on which society is based. It is not a passive state of mind but an active exercise of the will, and when it is exercised toward Christ, it involves an act of committal. It may even be an act of self-abandon. Then you don't believe it is going to be fine. Faith is not believing in spite of evidence, as has been said, but it is acting in scorn of consequences.
Faith is confident of things hoped for.
It makes no provision for failure. It risks something. It risks everything. Faith in the Lord Jesus Christ, which is the secret of the Christian life, is not having opinions about His person and His power and giving a mere intellectual assent to His claims. It is having a conviction of them amounting to an active interest that tests and tries them and puts them daily to the proof.
