Pretty familiar Bible Verse:
 

"This is the day the Lord has made.
We will rejoice and be glad in it.

~ Psalm 118:24 LAB

*

Bible Commentary:  "There are days when the last thing we want to do is rejoice. Our mood is down, our situation out of hand, our sorrow or grief overwhelming. We can relate to the writers of the psalms who often felt this way. But no matter how low the psalmists got, they were always honest with God about how they felt. And as they talked to God, their prayers ended in praise. When we don't feel like rejoicing, tell God how we feel. We will find that God will give us a reason to rejoice."

*

And the final verse (29) of chapter 118:
 

"Oh, give thanks to the Lord,
for He is so good!
For His lovingkindness is forever."

*
