I am listening to these songs by The Brooklyn Tabernacle Choir this morning, to cheer myself. The first video is an amazing rendition of Psalm 3. (Not to be confused with the metrical Psalter version, which our family sings regularly to the tune of "Our God our help in Ages Past." AKA St. Anne's.)
The second song is just to get you smiling and rejoicing.
Rejoice in the Lord alway: and again I say, Rejoice. Phil 4:4 KJV
