I'm trying to remember what my train of thought was when I first responded to you
Message 14.
I don't think I'd really claim any "fruitful works" as a direct mechanism for becoming spiritually attuned.
Works as used in the NT refers to actions, things you physically do (i.e. giving money to the poor, religious rituals, visiting the sick). There can be good works or bad works.
When something is fruitful it means it produces. So when you say fruitful works, all it says is that you did something. It doesn't mean that what you did is good or bad. Just whatever action you were doing produced what you were trying to do.
So no I wouldn't agree that belief/unbelief, love, lust, or pride are works.
I also wouldn't call the fruit of the spirit "works" either.
Galations 5:22-23
But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law.
IMO, the Holy Spirit operates within us to show us what needs to be changed (i.e. throw off the old). As those old unacceptable thoughts and behaviors give way to right thoughts and behavior we exude the fruit of the spirit. So as we mature spiritually our actions should show all the fruits of the spirit.
From what you've said concerning unbelief, pride, and lust; the Holy Spirit has brought to your attention thoughts and behaviours you need to work on. So you are at a point of deciding whether to do what is necessary to change or continue as you were.
But even though you are battling unbelief, pride, and lust; that doesn't mean you don't do good works or that you produce bad fruit. You're still working on finetuning your spirituality. It is a journey.
So in relation to the question in the OP:
Do people become spiritually attuned and ready for a meeting with God through our own efforts and behaviors, or do we become attuned and in common union (communion) with God through His Spirit and His grace?
I think it is a combination of the Holy Spirit and our own efforts. It is by our own effort that we decide to say yes or no to change.
