What is faith?
I think the whole concept of faith is one of the most misunderstood ideas that we have, misunderstood not only by the world but by the church itself. The very basis for our redemption, the way in which we are justified by God, is through faith. The Bible is constantly talking to us about faith, and if we misunderstand that, we’re in deep trouble.

The great issue of the Protestant Reformation in the sixteenth century was, How is a person justified? Luther’s controversial position was that we are justified by faith alone. When he said that, many of the godly leaders in the Roman Catholic Church were very upset. They said, “Does that mean that a person can just believe in Jesus and then live any way they want to live?” In other words, the Roman Catholic Church reacted fiercely because they were afraid that Luther’s view would be understood as an easy-believism in which a person only had to believe and never had to be concerned about bringing forth the fruits of righteousness. It was crucial that those who were involved in the Protestant Reformation carefully define what they meant by saving faith. So they went back and did their studies in the New Testament, specifically on the Greek word pistein, which means “to believe,” and they were able to isolate three distinctive aspects of biblical faith.

The first is the Latin term notitia: “believing in the data” or the information. It’s an intellectual awareness. You can’t have faith in nothing; there has to be content to the faith. You have to believe something or trust someone. When we say that a person is saved by faith, some people say, “It doesn’t matter what you believe, just as long as you are sincere.” That’s not what the Bible teaches. It matters profoundly what you believe. What if I believed that the devil was God? That wouldn’t save me. I must believe the right information.

The second aspect of faith is what they call assensus, or intellectual assent. I must be persuaded of the truthfulness of the content. According to James, even if I am aware of the work of Jesus—convinced intellectually that Jesus is the Son of God, that he died on the cross for my sins, and that he rose from the dead—I would at that point qualify to be a demon. The demons recognize Jesus, and the devil himself knows the truth of Christ, but he doesn’t have saving faith.

The crucial, most vital element of saving faith in the biblical sense, is that of personal trust. The final term is fiducia, referring to a fiduciary commitment by which I put my life in the lap of Jesus. I trust him and him alone for my salvation. That is the crucial element, and it includes the intellectual and the mental. But it goes beyond it to the heart and to the will so that the whole person is caught up in this experience we call faith.

Taken from Now, That’s a Good Question!
