If the best of my goodness is explainable in logical terms, it is likely that my goodness is a product of the Law rather than the fruit of obedience to the Spirit.
Am I critical? Then I have not yet seen the depth of my own depravity and I am still living under the illusion that my goodness is good enough. I need to see that even the best of who I am is like one dressed in filthy rags. “For all of us have become like one who is unclean, and all our righteous deeds are like a filthy garment; and all of us wither like a leaf, and our iniquities, like the wind, take us away.” Isaiah 64:6
