Above All, Faith. Ephesians 6:16 (KJV) says “Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked.” Paul tells us that above all, we are to use the shield of faith to stand against the wiles of the Devil. To the mature Christian, the importance of faith is most assuredly known. Yet the new creature in Christ needs to be built up in a faith that is most holy.
