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."
Reverend Robert W. & Mary C. Butler
