Trying to explain the nature of biblical faith can be quite a challenge. Several factors have contributed to this issue. First, a large majority of our culture are biblically illiterate. Also, many people have bought into the term "leap of faith." In their book Handbook of Christian Apologetics, Peter Kreeft and Ronald K. Tacelli give a summary of faith. It is very helpful.
Kreeft and Tacelli say we must distinguish between the act of faith from the object of faith- believing from what is believed. The object of faith means all things believed. For the Christian, this means everything God has revealed in the Bible. This faith (the object, not the act) is expressed in propositions. Propositions are many, but the ultimate object of faith is one. The ultimate object of faith is not words, but God’s Words (singular), indeed-Himself. Without a relationship with the living God, propositions are pointless, for their point is to point beyond themselves to God. But without propositions, we cannot know or tell others what God we believe in and what we believe about God.
The act of faith is more than merely an act of belief. We believe many things-for example that the Chicago White Sox will win this years World Series and that New Zealand is beautiful but we are not willing to die for those beliefs, nor can we live them every moment. But religious faith can be something to live every moment. It is much more than belief and much stronger, though belief is one of its parts or aspects. There are four aspects of faith:
1. Emotional faith: is feeling assurance or trust or confidence in a person. This includes hope (which is much stronger than a wish and peace (which is much stronger then mere calm.).
2. Intellectual faith: is belief. It is this aspect of faith that is formulated in propositions and summarized in creeds.
3. Volitional faith: is an act of the will, a commitment to obey God’s will. This faith is faithfulness, or fidelity. It manifests itself in behavior, that is, in good works.
4. Faith: begins in that obscure mysterious center of our being that Scripture calls the ‘heart.” Heart in Scripture does not mean feeling, or sentiment, or emotion, but the absolute center of the soul, as the physical heart is at the center of the body. “Keep your heart with all viligence” advised Solomon, “for from it flow the springs of life.” (Proverbs 4:23).
Joseph Thayer says,
"To believe" means to think to be true; to be persuaded of; to credit, [to] place confidence in. [And in] a moral and religious reference, pisteuein [from pisteuo] is used in the N.T. of a conviction and trust to which a man is impelled by a certain inner and higher prerogative and law of his soul. (Greek-English Lexicon of the New Testament, 511).
Biblical faith involves an objective element (the existence of God, Jesus' resurrection), and a subjective element (the individual must appropriate the objective truths through a subjective act). There have been three aspects of faith expressed throughout church history: notitia (knowledge), fiducia (trust), and assensus (assent). Notitia refers to the data or doctrinal element of faith. Assensus refers to the assent of the intellect of the truth of the Christian faith. According to the book of James, the demons can have intellectual assent to the fact that God exists but not have saving faith. That is why a person must exercise fiducia- this is the aspect of faith that involves the application or trust in the faith process. (1).
In other words, fiducia allows a person to go beyond merely intellectual assent. Fiducia involves the will, emotion, and intellect. In the Tanakh (the acronym that is formed from the first three parts of the Hebrew Bible: Torah (the first five books of the Bible), Nevi’ im (the Prophets), and K’ tuvim (the Writings), the Hebrew word for heart is "leb," or "lebad." While the word "heart" is used as a metaphor to describe the physical organ, from a biblical standpoint, it is also the center or defining element of the entire person. It can be seen as the seat of the person's intellectual, emotional, affective, and volitional life. In the New Testament, the word “heart” (Gr.kardia) came to stand for man’s entire mental and moral activity, both the rational and the emotional elements. Therefore, biblical faith also involves a commitment of the whole person.
Therefore, there is a relationship between belief that and belief in. As already stated, in James 2:19, it says that the demons believe that God exists. Apologetics may serve as a valuable medium through which God can operate, but faith is never the product of historical facts or evidence alone. It would make no sense for one to place his faith in God without believing that God exists. Objectively speaking, the Holy Spirit works in conjunction with the evidence for the truthfulness of the Christian faith to enable us to understand that God exists. However, from a subjective perspective, the Holy Spirit also enables an individual to place his trust in God. (John 16: 12-15).
A good example of this is seen in Acts 17:1-4, “And according to Paul's custom, he went to them, and for three Sabbaths reasoned with them from the Scriptures, explaining and giving evidence that the Christ had to suffer and rise again from the dead, and saying, This Jesus whom I am proclaiming to you is the Christ. And some of them were persuaded and joined Paul and Silas, along with a large number of the God-fearing Greeks and a number of the leading women." In this passage, we see that the Holy Spirit worked through the objective evidence (the Tanakh), which caused some of Paul's audience to not only acknowledge that Jesus is Jewish Messiah, but also to place their trust in Him for their salvation.
Faith and the resurrection: In 1 Cor 15: 1-17, Paul discusses the truth of Jesus' resurrection. It is important to note that a Christian's faith in the resurrection of Jesus will not change whether Jesus objectively rose from the dead in the context of time, space, and history. In other words, a Christian's faith cannot change the history of the past. The first followers of Jesus had a clear understanding about the relationship between faith and history.
As New Testament scholar Ben Witherington III says:
" Any position in which claims about Jesus or the resurrection are removed from the realm of historical reality and placed in a subjective realm of personal belief or some realm that is immune to human scrutiny does Jesus and the resurrection no service and no justice. It is a ploy of desperation to suggest that the Christian faith would be little affected if Jesus was not actually raised from the dead in space and time. A person who gives up on the historical foundations of our faith has in fact given up on the possibility of any real continuity between his or her own faith and that of a Peter, Paul, James, John, Mary Magdalene, or Priscilla. The first Christian community had a strong interest in historical reality, especially the historical reality of Jesus and his resurrection, because they believed their faith, for better or for worse, was grounded in it."
