It will bring faith. It will bring freedom. Faith comes from receiving the Word of God. So then faith comes by hearing, and hearing by the word of God. In English New Testaments, the words translated faith and believe are the same word in the Greek.
Faith is the noun form and believe is the verb form of the same Greek word.
Therefore I say to you, whatever things you ask when you pray, believe that you receive them, and you will have them. And whenever you stand praying, if you have anything against anyone, forgive him, that your Father in heaven may also forgive you your trespasses. Jesus is no respecter of persons. And his servant was healed that same hour. What the centurion believed determined what he received from God.
