I never said one word minimizing God's power. Every time humans plug into intercessory prayer --- like, Zuriel, please pray for my friend Roz's bad back --- God knows all about it and has always known all about it.
So why do we "do" intercessory prayer at all? Or, for that matter, why do we pray at all, since God knows everything before a word comes out of our mouth, even before a thought forms in our minds?
Answer that, and you've answered it all.
Oh, I believe the asking is certainly part of the design of God’s cummuning with us. I just believe the asking is done by those still living this mortal life.
I’m reminded of a time, as a teenager, asking my dad if I could go to town (we lived on a farm). My brother (having no say in the situation), sitting on the couch, turns to Dad and says: “Hey, Dad. He wants to go to town.” Dad said, “I heard him”.
