“Psalms reflect the expression of our hearts” 

Psalms are spiritual songs that connects us to God. One of the best times to sing Psalms is in the time of merry. This is not the time to take wine but a time to take Psalms and then you minister to the Lord! The Bible says 

James  5:13 Is any among you afflicted? let him pray. IS ANY MERRY? LET HIM SING PSALMS.

Is any merry? The Bible says let him, that is, that person should take Psalms. Scripture here addresses a person and it says to take Psalms. One thing is sure, as you take the Psalms to minister to the Lord, joy will come to your soul! Just minister to the Lord in Psalms!
