I'm wondering the same thing.
Canons 3-7 seem to simply be insisting on the recognition of "God's half" of the synergy equation.
I may be totally misunderstanding this, but it would seem to me that if anything, these canons sit quite well with the Orthodox Church's emphasis upon "apophatic theology", and that God is uncreated and being so, completely unlike the created order, and that in essence He is unknowable but known through His purposeful self revelation (via His energies.) That would mean then, quite clearly I'd think, that no amount of cleverness will lead one to anything save an idol - his fantasies about a "god" or something "bigger than himself". OTOH, the Scriptures teach that God gives light to sinners, that He knocks on the door of all men's hearts, etc. and that the real issue is how we respond to that quiet "rapping". St.John's Gospel says that we are given "grace for grace" or "grace on top of grace" depending on what translation you read, meaning that we're ascending a ladder - with each ascending rung being the result of our cooperation with the grace/light we've been given.
