Having been beaten with canes and locked in a jail, Paul and Silas, likely unable to sleep because of their wounds, began praying then singing to the Lord. Satan could not silence their joy. What Hell feared was that these two men would continue to make converts and cast out demons in Philippi. But beating and jailing them did not work, they continued to reach lost souls. This is what Hell feared, and the two men converted their jailor and his household, baptizing them and leaving the city with a healthy church in Philippi.
