Or thus: That they might have the joy spoken of above: That they may be one, as We are one. This His joy, i. e. bestowed by Him, He says, is to be fulfilled in them: on which account He spoke thus in the world. This joy is the peace and happiness of the life to come. He says He spoke in the world, though He had just now said, I am no more in the world. For, inasmuch as He had not yet departed, He was still here; and inasmuch as He was going to depart, He was in a certain sense not here.
