1I must go on boasting. Although there is nothing to be gained, I will go on to visions and revelations from the Lord. 2 I know a man in Christ who fourteen years ago was caught up to the third heaven. Whether it was in the body or out of the body I do not know—God knows. 3 And I know that this man—whether in the body or apart from the body I do not know, but God knows— 4 was caught up to paradise and heard inexpressible things, things that no one is permitted to tell. (2 Corinthians 12:1-4) New International Version (NIV)
Paul is writing about himself in the third person. The third heaven is where god dwells. The ancient Jews had several ways to describe the heavens. One way was to divide it into three parts. The first heaven is where the birds and clouds can be found. The second heaven is where thecelestial bodies can be found. The third heaven is where God can be found. Paul did not know “whether in the body or apart from the body” because he was not aware of his body. It’s not that his body was gone. It’s just that he didn’t pay any attention to his body. The word paradise can also be found in the gospel of Luke.
40 But the other criminal rebuked him. “Don’t you fear God,” he said, “since you are under the same sentence? 41 We are punished justly, for we are getting what our deeds deserve. But this man has done nothing wrong.” 42 Then he said, “Jesus, remember me when you come into your kingdom.” 43 Jesus answered him, “Truly I tell you, today you will be with me in paradise.” (Luke 23:40-43) New International Version (NIV)
Jesus is telling the criminal that the criminal will be in the presence of God because he believed Jesus. Paradise is synonymous with the Garden of Eden. According to the book of Genesis God was with Adam and Eve in the Garden of Eden or Paradise.
Paul’s description of his experience is very similar to a mystical experience. It is more than coincidental. Common among descriptions of mystical experiences is being in the presence of the divine. Another description is a sense of connectivity with all things. This would explain why Paul did not know “whether in the body or apart from the body”. Another similarity is the inability to articulate the experience.
