Isaiah 55:8-9

55:8 “Indeed, my plans are not like your plans,

and my deeds are not like your deeds,

55:9 for just as the sky is higher than the earth,

so my deeds are superior to your deeds

and my plans superior to your plans.

Romans 11:33-34

11:33 Oh, the depth of the riches and wisdom and knowledge of God! How unsearchable are his judgments and how fathomless his ways!

11:34 For who has known the mind of the Lord,

or who has been his counselor?
