In an almost backhanded way, in a clause I normally read right over, Paul comments to the Corinthians (as he tries to awaken their hearts and their checkbooks in 2 Cor 8-9) regarding their generosity that "a year ago you started not only to do this work but also to desire to do it" (8:10).
Two things Paul detects in healthy obedience: action and desire.
Action without desire = moralism. Desire without action = antinomianism. Desire + action = gospel obedience.
