In a sermon not long ago, I heard a definition of Biblical joy that I would like to share with you:

”Biblical joy is the conviction that God sovereignly controls the events of life for his glory and our good.”

I think of the words in James, “consider it all joy when you encounter various trials.” From this verse it seems as though joy is something that is not an unbidden emotion such as anger or jealousy. Joy seems to be something that needs to be learned through a changing of mindset.
