“‘To whom then will you compare Me, that I should be like him? says the Holy One‘ (Isa. 40:25). This question rebukes wrong thoughts about God.
‘Your thoughts of God are too human,’ said Luther to Erasmus. This is where most of us go astray.
Our thoughts of God are not great enough. We fail to reckon with the reality of His limitless wisdom and power.
Because we ourselves are limited and weak, we imagine that at some points God is too, and find it hard to believe that He is not.
We think of God as too much like what we are. Put this mistake right, says God. Learn to acknowledge the full majesty of your incomparable God and Saviour.”
–J.I. Packer, Knowing God (Downers Grove, IL: InterVarsity Press, 1973), 78-79.
