“Calvin, for example, spoke of faith as an ’empty vessel’ in order to stress its character as a receptacle that brings nothing to God but receives all things from Him.”
Christ & Covenant Theology — pg. 338
This is why I have said in the context of the past FV debate that faith does its proper work in Justification by resting in Christ for all while doing its proper work in Sanctification by working out all that Christ works in us.
Failing to think this way makes faith into a work whereby we use to trade in for the better model of Justification. In this direction lies neo-nomianism.
