The Holy Bible says,

Faith is being sure of what we hope for and certain of what you do not see. (Hebrews 11:1).

Without faith it is impossible to please God,

because anyone who comes to him must believe that he exist

and that he rewards those who earnestly seek him. (Hebrews 11:6).

My righteous one will live by faith.

And if he shrinks back,

I will not be pleased with him.

(Hebrews 10:38; Romans 1:17; Galatians 3:11; Habakkuk 2:4).

A faithful man will be richly blessed,....(Proverbs 28:20).
