I don't concern myself with matters too great or too awesome for me to grasp. (Psalm 131:1)

"LORD, my heart is not proud; my eyes are not haughty. I don't concern myself with matters too great or too awesome for me to grasp." (Psalm 131:1)
~I find it puzzling when theologians debate about issues like what divine eternality or divine foreknowledge actually means. I mean I can accept if they answer talks that limit God to this-worldly things; but, isn't it too far presumptuous to suppose that flesh and blood can write a book on how it feels to be an angel or a spirit; incredibly still, on how God perceives and experiences the world!!?
