There's a phrase used sometimes someone has gone off half cocked, which was an analogy referring to people using old firearms and not having it properly loaded or set correctly. It also referred to being half drunk or tipsy. Calvinistic theology is a very tipsy thing and it has taken verses from passages going off as we can say half cocked yes taking a truth like the natural man understands not the things of the spirit but they have not shown patience or restraint in getting the full picture of what was being said in the overall passage. The 1 Cor 2:10 verse has to do with the deep things of God the things that take spiritual maturity to perceive which comes with growth. Salvation truths ARE NOT deep things of God and Paul calls them MILK and not MEAT.
And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ. 2I have fed you with milk, and not with meat: for hitherto ye were not able to bear it, neither yet now are ye able. 1 Cor 3:1
So clearly he could not speak unto them of deep spiritual truths for they were walking too much like natural men. But to them he said back to the milk that is the basic salvation truths
for that is what you and all men can at least understand.
So again what you have with Calvinists is their cherry picking one small verse from 1 Cor 2 (natural man understands not the things of the Spirit) and going off with it as we could say half cocked and thinking they've got the smoking gun against the more reasonable ;understanding of scripture and that is natural men can understand the gospel and it's meaning enough to act upon it.
