Faith to believe in the unseen, no matter what others may say or do to try to persuade us otherwise, is the kind of faith we must have in God.
Believe in God because He will be with you through everything including all difficult situations.
Hebrews 11:1, 6
Now faith is being sure of what we hope for and certain of what we do not see.
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.
