Why did the Philippian jailer approach Paul and Silas among all his prisoners?
God sovereignly let the pagan jailer know that Paul and Silas were the answer to his dilemma. Although his prisoners were loose and could flee, they stayed, and his deeper need was his own soul. He approached them because God revealed they held the salvation he desperately needed.
Les explains that the jailer was a pagan Gentile, and he singled out Paul and Silas from all his prisoners because God sovereignly let him know they were the answer to his dilemma. His dilemma was that all the renegade prisoners were loose and ready to flee, yet they were not fleeing; they were staying. Les suggests God was letting the jailer know the answer to his problem was not merely a bunch of prisoners but the man's own soul. The jailer then brought Paul and Silas out of the dungeon and asked, "Sirs, what must I do to be saved?" Les contrasts this with Peter's preaching in Acts 2 to the covenant nation of Israel, who asked what the nation must do, whereas Gentiles are dealt with as individuals, each asking what must I do to be saved.
