John Chrysostom
Now He does not rejoice and give thanks because the mysteries of God were hid from the Scribes and Pharisees, (for this were not a subject of rejoicing, but of lament,) but for this cause gives He thanks, that what the wise knew not, babes knew. But moreover He gives thanks to the Father, together with whom He Himself does this, to shew the great love wherewith He loves us. He explains in the next place, that the cause of this thing was first His own will and the Father’s, who of His own will did this. As it follows, Even so, Father; for so it seemed good in thy sight.
But after He had said, I thank thee that thou hast revealed them to babes, lest you should suppose that Christ was destitute of the power to do this, He adds, All things are delivered to me of my Father.
