Salvation is by grace. Salvation is ουκ εξ εργων, not of works. A Christian Minister’s job is to preach salvation by grace by grace (Ephesians 2:8-9). Christian preaching is not of works. For a minister, preaching and theology must walk hand in hand; the content of the message (grace) should characterize the mode (preaching done by grace and not of works). Otherwise, a minister will never make Christ “all.”
