Why was Saul of Tarsus carnal and fleshly even though he was religious?
Saul of Tarsus was carnal and fleshly because, despite his religion, the motivating power within him was not pleasing to God. He opposed God's purposes by stamping out those who recognized Jesus as the Christ, unable to believe Jesus was the promised Messiah.
Les teaches that Saul was carnal and fleshly even though he was religious, because the motivating power within him was not the things that were pleasing to God, but quite the contrary. He was stamping out those who had recognized Jesus was indeed the Christ. Les explains this reflects the mindset of not only Saul of Tarsus but all the religious Jews of Jesus' day: they were so constantly against Him because they could not believe He was the Christ, that He could be the one promised all the way back from Genesis chapter 12.
