12:1-6 There can be no doubt the apostle speaks of himself. Whether heavenly things were brought down to him, while his body was in a trance, as in the case of ancient prophets; or whether his soul was dislodged from the body for a time, and taken up into heaven, or whether he was taken up, body and soul together, he knew not. We are not capable, nor is it fit we should yet know, the particulars of that glorious place and state. He did not attempt to publish to the world what he had heard there, but he set forth the doctrine of Christ. On that foundation the church is built, and on that we must build our faith and hope. And while this teaches us to enlarge our expectations of the glory that shall be revealed, it should render us contented with the usual methods of learning the truth and will of God.

4. unspeakable—not in themselves, otherwise Paul could not have heard them; but as the explanation states, "which it is not lawful … to utter" [Alford]. They were designed for Paul's own consolation, and not for communication to others. Some heavenly words are communicable (Ex 34:6; Isa 6:3). These were not so. Paul had not the power adequately to utter; nor if he had, would he have been permitted; nor would earthly men comprehend them (Joh 3:12; 1Co 2:9). A man may hear and know more than he can speak.
