Making the simple wise

When I was typing up the previous post with the Psalm about God making the simple wise, I wondered: How many ways can you take that? When God's word makes the simple wise -- specifically focusing on how it does that for the simple -- does that mean it does nothing for those who are already wise in their own eyes? Is it saying that the ones who can be made wise are the simple ones, the ones who come as little children, teachable and open? That the things of God are hidden from the "wise and learned" and revealed to little children? The Bible keeps saying not to be wise in our own eyes. When we are wise in our own eyes we are not teachable; it's a matter of pride. It's spiritually dangerous to be impressed with our own wisdom. Learning follows from humility.
