Faith is the assurance that the things revealed and promised in the Word are true, even though unseen, and gives the believer a conviction that what he expects in faith, will come to pass. ... In other words, it becomes so tangible that you now possess it. It becomes a reality in the spiritual realm. Faith makes people great. The world survives because it has faith. People's lives are the result of whole faith.The purpose of faith is to act as a measure of a person's hope, and to help a person grow in his or her trust in God the Father and in God's purposes for us as his children. The Apostle Paul said that faith, hope, and charity (the pure love of God) are key attributes of being in eternal life.
