So I leave it to y’all to decide whether scripture indicates that Adam had the sort of faith that compels action (like Abraham drawing a blade or Daniel praying in his window knowing the consequences) or the sort of faith that compels inaction (like the demons who believe and tremble).
I like your thought provoker.
Since John Calvin's formulation of
"faith is coming before God empty" really resonates with me. It seems to me that what the demons had/have is not this kind of faith. If it is true that the sin of pride was the first sin for the devil. Then I think it would follow that although the devil 'believed' he lacked 'faith' (Calvin's type). For he no longer came before God empty, but with pride, puffed up, etc.
I suppose the question is, in Adam's case, does coming before the Lord 'empty' constitute 'action' or 'purpose' or 'will'? If Adam came before the Lord (walked with him in the garden) empty, and the Lord was pleased with this, was this a presenting of oneself as empty through 'purpose'... or through ignorance the ignorance of any other option? I tend to lean toward the former.
So for me, it seems that although salvation faith and pre-fall faith might have some differences (I think they do). The one thing that is not different is the 'emptiness' that is required of the self to God. This, I think, would seem to be a universal, throughout all ages, commonality. So in this sense, Adam was to bring faith.
As an added edit. I also think this type of presentation to the Lord, bringing oneself as empty, also includes love for God (first commandment).
Keep seeking God's truth as if it were hidden treasure.
