“How joyful is the one whose transgression is forgiven, whose sin is covered! How joyful is a person whom the Lord does not charge with iniquity and in whose spirit is no deceit!”
Psalms 32:1-2 CSB
There is always a reason for joy when you know you’re forgiven.
I used to sing a song that says, “I get joy when I think about what He’s done for me.”
Don’t let your joy come from anything else.
