What you read affects what you believe. When you feed the Word of God into your spirit man and renew your soul (mind), faith comes alive and becomes a living force within you.
Read the Bible. Read books that stir your faith in the God of Heaven. Nurture the Seed of Faith inside you. Acorns become oak trees.
“So then faith cometh by hearing, and hearing by the word of God.”
(Romans 10:17)
