In the story from Acts 16, we're given several layers of captivity sprinkled with a host of ironies. From the opening with a slave girl prophetess for the Temple of Apollo dogging the apostle Paul and his group, the contrasts are at play and the story continues.
After she has the "spirit of the snake" cast out, is freed, then Paul and his fellows are imprisoned. At their opportunity for liberation, they pass it up, ministering instead to the jailer who comes to recognize his own captivity. The liberation is complete as the jailer and his household come to faith in the way of Jesus' good news of new life.
In John, a less elaborate story has Jesus engaged with Jewish believers. He teaches them about their captivity, to which they protest. He insists that knowing his truth will set them free like nothing else.
