This is the day which the Lord hath made; we will rejoice and be glad in it. Psalms 118:24
There are days when the last thing we want to do is rejoice. our mood is down, our situation out of our hand, our sorrow or guilt overwhelming. We can relate to the writers of the psalms who often felt , they were always honest with God. And as they talked to God, their prayers ended in praise. When you don't feel like rejoicing, tell God how you truly feel. You will find that God will give you reason to rejoice.
