A self assured saint is of no value to God. He is abnormal, unfit for daily life, and completely unlike God.
We are here, not as immature men, but as men and women, to do the work of this world. And we are to do it with an infinitely greater power to withstand the struggle because we have been born again from above.
What God wants us to do is to "walk by Faith." We must never consider our moments of inspiration as the standard way of life, our work is our standard.
