1. So faith comes from hearing, and hearing through the word of Christ.Romans 10:17
2. And without faith it is impossible to please him, for whoever would draw
near to God must believe that he exists and that he rewards those who
seek him. Hebrews 11:6
3. Now faith is the assurance of things hoped for, the conviction of things not seen. For by it the people of old received their commendation. By faith we understand that the universe was created by the word of God, so that what is seen was not made out of things that are visible. By faith Abel offered to God a more acceptable sacrifice than Cain, through which he was commended as righteous, God commending him by accepting his gifts. And through his faith, though he died, he still speaks. By faith Enoch was taken up so that he should not see death, and he was not found, because God had taken him. Now before he was taken he was commended as having pleased God. Hebrews 11:1-13:25
For me, Faith is believing that the word of God is God and it is life. I believe that the word of God lives in the life of anyone who sincerely seek the face of God through hearing the word of Faith.
