Trusting in God's testimony is receiving all that God has given to us. Faith viewed philosophically must be regarded as lying at the base of all knowledge. The devils believe and tremble. The truths of revelation are in many cases above reason, but can never be considered as opposed to it. Come, let us reason together, saith the Lord.
Faith is the assent of the understanding to any truth.
Religious faith is assent to any truth of divine revelation and of the events and doctrines contained in it. True faith is an essential grace, and a main-spring of Christian life. By it the Christian overcomes the world, the flesh, and the devil, and receives the crown of righteousness.
