Paul writes: "But when if pleased God, who had set me apart, even from the womb" at the start of Galatians 1:15. The question is "in what way was Paul set apart?" For salvation? Nope. As a Hebrew? Perhaps. As a person who would become a prophet, a spokesperson of God? Probably. Paul continues: "and called me through His grace," refers to his Damascus road experience. So this refers to when God's Son revealed Himself to Paul and asked Paul why he was persecuting Jesus. This then refers to when God revealed His Son "to" Paul. And now to the heart of the matter, "was pleased to reveal His Son in me" refers to Paul receiving the "pure gospel," not from men but from God, for the purpose of Paul being God's agent to reveal His Son to others. "that I [Paul] might preach His among the Gentiles," Nothing in this passage says or suggests God compelled Paul to believe, but rather the Lords startling appearance caused Paul to reconsider to direction and repent. Neither "irresistible grace" nor "prevenient grace" (if thought to supernaturally endow the capacity to believe) is in view.
