“Oh, the depth of the riches and the wisdom and the knowledge of God!
How unsearchable his judgments and untraceable his ways!
For who has known the mind of the Lord?
Or who has been his counselor?
And who has ever given to God, that he should be repaid?
For from him and through him and to him are all things.
To him be the glory forever. Amen.” (Romans 11:33-36)
I love how this is subtitled “A Hymn of Praise” in my Bible, as Paul beautifully sums up how he feels about the complex, mysterious, yet wonderful things he had expounded on thus far.
I think this would be the perfect hymn to turn to both when when you are in complete awe of God, and when you believe yet are struggling to understand.
