Adam Clarke on John 3:21

Wrought in God - In his presence, and through his assistance. This is the end of our Lord's discourse to Nicodemus; and though we are not informed here of any good effects produced by it, yet we learn from other scriptures that it had produced the most blessed effects in his mind, and that from this time he became a disciple of Christ. He publicly defended our Lord in the Sanhedrin, of which he was probably a member, Joh 7:50, and, with Joseph of Arimathea, gave him an honorable funeral, Joh 19:39, when all his bosom friends had deserted him.
