Acts 16:29

Then he called for lights, and sprang in, and came trembling, and fell down before Paul and Silas; and brought them out, and said, Sirs, what must I do to be saved? Do you mark how the wonder overpowered him? And having called for lights, it says, he sprang in, and fell down at the feet of the prisoner; he, the prison keeper, saying, Sirs, what must I do to be saved? Why, what had they said? Observe, he does not, on finding himself safe, think all is well; he is overcome with awe at the miraculous power.

Do you mark what happened in the former case, and what here? There a girl was released from a spirit, and they cast them into prison, because they had liberated her from the spirit. Here, they did but show the doors standing open, and it opened the doors of his heart, it loosed two sorts of chains; that prisoner kindled the true light; for the light in his heart was shining. And he sprang in, and fell before them; and he does not ask, How is this? What is this? but straightway he says, What must I do to be saved?

From this event it can be established that the faith of people is something in their power. See how, after such a fright, only the jailer believed. And yet, most of all, those imprisoned should have been moved to believe, since they had experienced a greater wonder when they saw their iron chains suddenly broken. Being foolish, they were frightened at the moment when the foundations of the prison were shaken and the doors were opened. But being despisers of God, after such a sign, they forgot what had happened, so that they did not speak to the jailer or to anyone about the terror that had happened. For, no doubt, had they heard from the jailer or from the followers of Paul the reason for such a wonder, they would perhaps have been converted. I think that a similar event happened in hell, when our Lord Jesus Christ, the Word of God, descended there tasting death for a brief time. The foundations of the earth were shaken and the chains of all were loosed. Whoever went to meet the Savior and believed in him was saved like the jailer and his house. Whoever rejected him and did not endeavor to investigate the strange miracle stayed in hell. Just as those who followed Paul, after the chains were loosed, came out of the prison in the morning, so Christ, coming back from hell in the dark of earliest morning and having been freed—as it was not fitting for him, being God, to be held by death—arose, and in the first place appeared to his faithful disciples and the women around Mary, and comforted them and confirmed them in faith by saying, "Take heart." He was then assumed into heaven, where he remains with God his Father. Likewise, the followers of Silas, who came out of the prison, visited Lydia and the brothers and departed.
