Faith is the reality of what we hope for, the proof of what we don’t see.
Hebrews 11:1 (CEB)
And it is impossible to please God without faith. Anyone who wants to come to Him must believe that God exists and that He rewards those who sincerely seek Him.
Hebrews 11:6 (NLT)
For I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith.
Romans 12:3
So then faith cometh by hearing, and hearing by the Word of God.
Romans 10:17
