Jesus Christ, the Son of God, rejoices in the perfect will of the Father who ordains and arranges all things. He calls him ‘Lord of heaven and earth’, a reference to his supreme sovereignty.
Christ’s joy is also our joy, and our strength. He shows us how to find peace and optimism in this fallen world. All our hope is in God. As weak and helpless human beings, we can only look to God to act. We cannot advise him or teach him; we cannot help him or encourage him; we can only wait for him to do his work, a work which is utterly beyond our power. Certainly, we have a work of witness to do, but what Christ here thanks the Father for doing is beyond all created power. So we give thanks for it, because we know that it is accomplishing so much. God the Father pours all his wisdom into this work and it is a perfect work that will bring about a perfect result, even out of the dreadful state of this world. How many perfect things are there that the believer can take delight in? None that come from man, or that are natural, for nature has been touched in every part by the curse, but the curse does not in any way touch the secret work of God which goes on regardless.
Thou has hidden – and revealed – an illustration of regeneration. He does not mean that only babes understood, but that God is at work humbling men and women and showing himself to them.
