Faith is the substance of things hoped for. (Hebrews 11:1)

Faith is the real substance, or mental understanding, which stimulates and clears our mind, . We cannot hold it in our hands, or walk on it with our feet, but it becomes strength to our minds as we progress in the knowledge of God. And, as we gain more understanding of God's promises through study, fellowship, and prayer, our faith increases. Hebrews 10:23
