Prison

According to the tradition, this is where Paul and his companion Silas spent the night:

After they had given them a severe flogging, they threw them into prison and ordered the jailer to keep them securely. Following these instructions, he put them in the innermost cell and fastened their feet in the stocks. About midnight Paul and Silas were praying and singing hymns to God, and the prisoners were listening to them. Suddenly there was an earthquake, so violent that the foundations of the prison were shaken; and immediately all the doors were opened and everyone's chains were unfastened. When the jailer woke up and saw the prison doors wide open, he drew his sword and was about to kill himself, since he supposed that the prisoners had escaped. But Paul shouted in a loud voice, "Do not harm yourself, for we are all here." The jailer called for lights, and rushing in, he fell down trembling before Paul and Silas. Then he brought them outside and said, "Sirs, what must I do to be saved?" They answered, "Believe on the Lord Jesus, and you will be saved, you and your household." They spoke the word of the Lord to him and to all who were in his house. (Acts, chapter 16:23-32)

How are these healing charts significant for understanding the world of Paul?

Paul was imprisoned numerous times. At one point he writes, concerning the Gospel:

...for which I suffer hardship, even to the point of being chained like a criminal. But the word of God is not chained. (2nd letter to Timothy, chapter 2:9)

Both Paul's words and the record of events in Acts remind the reader of the cost of being a Christian, especially a missionary in the 1st century. The fact that Paul's letters remain with us today shows how truly, the word of God is not chained!
