For my thoughts are not your thoughts, neither are your ways my ways, declares the Lord. 9 For as the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts. (Is 55:8-9)
This verse is quoted to make a variety of points. Some quote it to make the point that God is unknowable. Others use it to argue that we can’t understand God’s will and way of thinking. My favorite use of this verse, however, is in a debate when someone’s position is being challenged and they don’t know how to respond. When all else fails, just claim that your point of view is too lofty to understand because it comes directly from God!
