Ephesians 5:19-20 (Amplified Bible)
19 Speak out to one another in psalms and hymns and spiritual songs, offering praise with voices [and instruments] and making melody with all your heart to the Lord,
20 At all times and for everything giving thanks in the name of our Lord Jesus Christ to God the Father.
I think this verse tells us exactly what we should do at all times no matter what our circumstances are. Nothing I could write would say it any better or make it any plainer. Read the word of GOD. It says it all!!
