Ephesians 6:16 - Shield of Faith!

Ephesians 6:16 -  The Interpreter's Bible Exposition Commentary (1953) aptly recognizes: "Orthodox Christianity is right in its bold assertion that the root of sin is not weakness but unbelief.  Faith is the only real cure.  The Reformers were right also in confronting all works-religion with a return to the good news of "justification by faith."  Rehearsal of the great Reformation argument cannot be attempted here. The relevance of the concept, even in its most general form, to the problem of Christian ethics cries out for rediscovery.  The deeper problem raised by human sinfulness is not the what, but the why."
