Our God is a FAITH God.  He created everything by faith and His faith is in you.

When you need healing, you don't do it on your faith.

You have faith because you have a spirit.  Romans 10:17 says that you get this faith built up by hearing the Word.

Romans 10:17 KJV ... So then faith cometh by hearing, and hearing by the Word of God.

Romans 10:17 AMP ... Faith comes by [what is told], and what is heard comes by the preaching [of the message that came from the lips] of Christ the Messiah [Himself].

Romans 10:17 NLT ... Faith comes by hearing ... the Good News about Christ.

Here's a footnote by Kenneth Copeland on this verse: "and you will know the Truth, and the Truth will make you free."
