Best not to butt in, Robert, especially when you do not know what or who you are talking about.
If Paul wanted to reject the call of the Lord then he was never called and Scripture would give us an entirely different accounting.
Those salvifically called are quickened from death to life (Eze. 36:26; Romans 8:30). Those so called will want to accept the call per their own free will—their greatest inclinations at the moment they so choose—for their greatest inclinations at the instant of their quickening are to not not reject the call.
As Romans 8:30 teaches, no one rejects the salvific call of the Lord.
God does as He pleases, only as He pleases, always as He pleases. None can thwart Him, none can hinder Him. So His own Word expressly declares: "My counsel shall stand, and I will do all My pleasure" (Isa 46:10); "He doeth according to His will in the army of heaven, and the inhabitants of the earth: and none can stay His hand" (Dan 4:35).
