Worship the Lord with gladness; come before him with joyful songs.
God is good and giving him grateful praise through songs is a beautiful way to worship him during your prayer time and it also refreshes your soul. It doesn’t matter how well you sing; what matters is that it comes from your heart.
About midnight Paul and Silas were praying and singing hymns to God, and the other prisoners were listening to them.
Paul and Silas were in a pretty bad situation, they were in prison, but they kept praying and singing to God. No matter what the situation you find yourself in keep praying and singing to God. Keep praising God until he gives you the victory.
