I want to break this up into two devotionals, because there is so much here.

Acts 16
25 But at midnight Paul and Silas were praying and singing hymns to God, and the prisoners were listening to them. 26 Suddenly there was a great earthquake, so that the foundations of the prison were shaken; and immediately all the doors were opened and everyone’s chains were loosed.

First off, Paul and Silas are in the INNER prison. From my quick reading long term incarceration was not common in Rome. More common was horrible punishments and awful executions.
So here they are awaiting some very awful things, their thoughts could have run wild. They choose to sing hymns and worship God. The other prisoners are listening.
Then an earthquake free’s them from their bondage.

This is what happens in the spirit realm when we choose to worship and honor God.This is how we free ourselves from the stress and pressure of life. Worship the king.
