Humans conceptualizing God IS putting limits on him..
Or the "walls" of the sheep pens (John ch 10)...
Which Jesus called them out of..
Studying the Universe does not have to be conceptualizing God, similarly reading the Bible does not "conceptualize" God as some abstraction.
The Universe can be read and studied as the Bible is read and studied.
I'm am not saying that we should take One over the other, that would imply that one is contradicting the other and they do not, they can't.
