Works done before the grace of Christ, and the Inspiration of his Spirit, are not pleasant to God, forasmuch as they spring not of faith in Jesus Christ; neither do they make men meet to receive grace, or (as the School-authors say) deserve grace of congruity: yea rather, for that they are not done as God hath willed and commanded them to be done, we doubt not but they have the nature of sin.
Another one I like. I still believe in total depravity. This means, naturally, that even “good works” performed by those who reject Jesus, are as filthy rags. It is a tough one to get past, because we like to attribute goodness to people. I am of the mind that there are no “good people”. This has liberated me, in the sense that I have an ability to appreciate people for who they are. There is no demand for me to judge based on works. If not for Christ, no one is capable of good.
The article that follows, amplifies this for me. The statement is basically that even after you are working under the blessing of Christ, making a statement out of your works is also filth.
