What is meant by faith?

"It is to feel in good earnest that we are creatures of God; it is a practical perception of the unseen world; it is to understand that this world is not enough for our happiness, to look beyond it on towards God, to realize His presence, to wait upon Him, to endeavour to learn and to do His will, and to seek our good from Him. It is not a mere temporary strong act or impetuous feeling of the mind, an impression of a view coming upon it, but it is a habit, a state of mind, lasting and consistent. To have faith in God is to surrender one’s self to God, humbly to put one’s interest, or to wish to be allowed to put them into His hands who is the Sovereign Giver of all good."

John Henry Newman
