When did Paul go on his first missionary journey and when did he write 2 Corinthians?
Paul was likely on his first missionary journey in about AD 41 or 42, during which he was stoned at Derbe. He wrote 2 Corinthians in about AD 60. These dates are presented as fitting the chronology of his being caught up to the third heaven.
Les ties the stoning at Derbe chronologically to Paul's experience in 2 Corinthians. He explains that Paul was probably in about 41 or 42 AD when he was on that first missionary journey, and that Paul wrote II Corinthians in about 60. Les says this chronological fit supports that when Paul was stoned at Derbe and dragged out for dead, he then had a tremendous opportunity to see the glories of Heaven. Les thinks it is pretty obvious Paul was out of the body, with the body lying outside Derbe after being stoned, while his soul and spirit took flight and he was caught up to the third heaven.
