Well, God knows ...and He wants us to understand what He feels is vital for us to know.

And that vital piece of information is ...that He loves us.

Isn't that what healthy parents show their newborn baby from the onset of birth??

And even when our children get older, we can't tell them everything we've learned through life ...and furthermore, if we attempted to, they'd be overwhelmed and often wonder what all that we are saying has to do with their present concerns.  Often they have to get through the moment before they understand it, as their thoughts are dominated by emotions which rule before reason can enter in. Mostly they need to just know we are there ...and that we continue to love them. And it is so valuable to us that they still come to us with their concerns, bringing love to full circle.

So, we realize that all of us understand to different degrees ...whether we are parents or children.  And our degree of knowledge often is influenced by our focus ...or field of study.  

But, be certain of the fact that the most intelligent and most renowned brain surgeon in the world doesn't understand the human brain like God does.
