Faith is defined as belief, confidence or trust in a person , object, religion, idea or view despite the absence of proof. Faith does not necessarily involve the abandonment of reason, but acknowledges more or less consciously the fact that a proof is not possible in a given context. Faith within Christianity is based on the works and teachings of Jesus Christ. Christianity declares itself not to be distinguished by faith, but by the object of its faith. Rather than being passive, faith leads to an active life aligned with the ideals and the example of the life of Jesus. The Christian sees the mystery of God and his grace and seeks to know and become obedient to God. To a Christian, faith is not static but causes one to learn more of God and to grow; Christian faith has its origin in God.
In Christianity, faith causes change as it seeks a greater understanding of God. Faith is not simple obedience to a set of rules or statements. Before Christians have faith, they must understand in whom and in what they have faith. Without understanding, there cannot be true faith, and that understanding is built on the foundation of the community of believers, the scriptures and traditions and on the personal experiences of the believer. In English translations of the New Testament, the word “Faith” generally corresponds to the Greek noun pistis or to the Greek verb pisteuo, meaning “no trust, to have confidence, faithfulness, to be reliable, to assure.”
In the New Testament, faith is the comprehensive concept for the relationship between God and human beings on the basis of God’s saving activity for, in, and through Jesus Christ. In Jesus’ preaching faith is a pre-condition for his miracles, for his cures, and for the forgiveness of sins.
