Faith is confidence in what we hope for an assurance about what we do not see
Faith is defined as belief with strong conviction; firm belief in something for which there may be no tangible proof; complete trust, confidence, reliance or devotion. Faith is the opposite of doubt.
Hebrews 11:6 states, “And without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him.”

What else does the bible say about faith?
Consequently, faith comes from hearing the message, and the message is heard through the word about Christ.
If you believe, you will receive everything that you ask for.
For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God— not by works, so that no one can boast.
Trust in the Lord with all your heart and lean not on your own understanding; in all your ways submit to him, and he will make your paths straight.
Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ, through whom we have gained access by faith into this grace in which we now stand. And we boast in the hope of the glory of God. Not only so, but we also glory in our sufferings, because we know that suffering produces perseverance; perseverance, character; and character, hope. And hope does not put us to shame, because God’s love has been poured out into our hearts through the Holy Spirit, who has been given to us.
