What's not of grace, is not of God. And what's not of God, does not edify or profit the body of Christ... because what's not of grace, is of man. And what's from man and for man has a single purpose... and that is to simply to make man shine, but not for the glory of God.
And while we're dealing with the gifts let me give you a tool or a way of getting the pulse on Romans 12, Ephesians 4, 1 Corinthians 12, 13 and 14, that you may not have thought of before. Corinthians gives us a simple outline to help you understand the message of these three chapters. And the context, as with all Scripture, is fundamental. And the context is specifically dealing with the gifts of God's Spirit and how he graces us with all we need, in the Body of Christ, to accomplish His mission upon the earth.
