The truth is that, all of these systematic (and some more unsystematic) theologies are something that a regular streetsweeper would never come up with if you just handed him a Bible
It takes massive amounts of mental gymnastics to come up with both arminianism and calvinism. Both are full of unbiblical language like "effectual call, ineffectual call, prevenient grace" etc.
These were scholars who came up with this, NOT PLUMBERS. Im sure of that.
Not knocking the scholars, im sure many of them love the Lord and contribute greatly, but I feel sometimes, they tend to overcomplicate things
Once you try and define things to throughly you fall into the world of assumptions, which the more you look build on other assumptions, and you then have a whole new faith structure. Some modern day people who are less connected with scripture end up with a different faith entirely.
They all seem to be looking for something more than the words applied to the human cleansed heart. And maybe that is our real problem, until we know real openness and vulnerability, speaking from the depths of our being, the importance of things makes less sense, and theories of steps of theology become more interesting.
Certainly until my heart came more alive, theories and ideas seemed more interesting and real.
