Faith is not an excuse to justify impotent doctrines, nor is it blind acceptance of what we're taught. True faith must be coupled with the power of God. Holiness is powerful. There is power in their life. It is no coincidence that some of the most humble men of God, men like David Wilkerson, Rick Joyner, Paul Cain, and many others, are also some of the most powerful.
Humility precedes holiness which precedes power.
The ability to become holy is a result of first being humble. The life I live in the body, I live by faith in the Son of God, who loved me and gave himself for me. Becoming Christlike is not an overnight process. It is an unfolding experience wherein the old parts of our lives are crucified and resurrected in the image of Him. Then, as we are transformed into the likeness of Christ by being made holy even as He is holy, we will find the power we lack.
