Faith is believing in something in which there is no proof. A complete trust in God. Faith, which is believing is an act. It is an action. You act on what you believe. No action, no faith.
Look unto Jesus,the author and finisher of our faith. Faith by itself, if it does not have works is dead. Be ye doers of the word and not hearers only deceiving yourselves.
Beloved, faith is an action.
