What was the outcome of Paul's three years alone with the Ascended Lord?
The outcome was that Paul emerged prepared as the apostle to the Gentiles, equipped not with Judaism or Law but with Grace. He received the doctrines of grace and the Gospel of Grace: that Jesus is the Christ, the Son of the Living God, who died for sins, shed His blood, was buried, and rose from the dead.
Les explains that Paul's three years alone with the Ascended Lord functioned as a private seminary in Arabia, with no one but himself and the Lord so far as we know. It was a long time, but he had much to soak up. Out of those three years came an apostle prepared to go to the Gentiles—not with Judaism or Law, but with Grace. He was not sent with only the Gospel of the Kingdom that Jesus was the Christ, but with the Gospel of Grace: Jesus is the Christ, the Son of the Living God, who died for our sins, shed His blood, was buried, and rose from the dead. That is all Paul could write about and talk about.
