Faith is the belief in things that cannot be proven through science or through the senses. It is the belief that things will happen in a certain way even though there is no logical reason to believe that they will.
When we look at these ideas in connection with Christian belief, their meaning is clearer. We cannot prove through science or through our senses that there is a God who cares about us and loves us. If we believe, we believe because of faith. We have no logical reason to believe that all humans will be judged and will be rewarded or punished based on their conduct and beliefs in this life. If we believe, we believe because of faith.
Faith, then, is the firm belief that certain truths exist even though there is no way of proving them.
In Hebrews, Chapter 11, in the New Testament, Paul devotes an entire chapter to the subject of faith, beginning with the famous verse: "Now faith is the substance of things hoped for, the evidence of things not seen." Paul names a great many of the historical figures from the Old Testament, including men like Noah and Abraham, and explains how faith was the central element in their lives. This chapter is not only beautifully written but authoritative on the subject of faith. It would seem that faith consists of reliance on feeling or intuition rather than on reason or material evidence.
Faith is the aspect of having a strong belief in something and can be said to be slightly higher and stronger than hope. in faith we have a conviction of what we believe in.
In religion faith in the Bible is saids to move mountains, this shows the intensity of the expectation. it is the inner patience with great expectation of an occurrence to take place as expected.
Faith can also be said to be purity of one's deeds and complete trust of the other partner as in faithfulness when it comes to marriage.
