What do you mean when you say not to 'reason'?
"Come now, let us reason together," says the LORD.
It doesn't say that at all though.
Jesus OFTEN asked men "what do you think"
It's what we shall eat or drink or our life that we
should "give no thought" to....
God does indeed want us to "think"
He said He gave us a sound mind.
Again:
Not to be disagreeable but God DOES desire that we
have understanding, all of us (proverbs 4 says so)
yet most do NOT have understanding... So if it worked
as you're suggesting... we'd all have understanding.
Evidently we need to "get" understanding, as it says
in proverbs (God's Word)
GET wisdom GET understanding...
