You are arguing against a strawman here. this is your confusion over flesh and Spirit. Doing works is not necessarily flesh. Works of faith or through faith is NOT flesh, but still works.
Was this not true with Christ? God the Father did all the work through him?
John 14:10 Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works
Whomn did teaches trust all the time to do what? Did Christ not send us the same Holy Spirit of truth to guide us and lead us as the same Holy Spirit led Christ?
So who does the works, you or God? You already answered this once and claimed you, are you still right and more righteous than God like those two men that went into the temple?
One was Justified and the other not, who was justified?
Luke 18:10 Two men went up into the temple to pray; the one a Pharisee, and the other a publican.
So what justifies God or you?
