Rom 11:33-36
O the depth of the riches of the wisdom and of the knowledge of God! How incomprehensible are his judgments, and how unsearchable his ways! For who hath known the mind of the Lord? Or who hath been his counsellor? Or who hath first given to him, and recompense shall be made him? For of him, and by him, and in him, are all things: to him be glory for ever. Amen.
This exclamation springs from the depths of St. Paul’s heart, as he recognises God’s marvellous designs in spite of the obstinacy of the people of Israel, most of whom did not recognise the Messiah. Paul was granted a profound knowledge of God, and to prevent him from falling into presumption the Lord allowed him to undergo a certain suffering, which he himself describes as a “thorn” in his flesh (cf. 2 Cor 12:7).
