Romans 11:33-36 — from biblegateway.com

Oh, the depth of the riches of the wisdom and[a] knowledge of God!
    How unsearchable his judgments,
    and his paths beyond tracing out!
34 “Who has known the mind of the Lord?
    Or who has been his counselor?”[b]
35 “Who has ever given to God,
    that God should repay them?”[c]
36 For from him and through him and for him are all things.
    To him be the glory forever! Amen.
