There's a big difference between the joy we get from Christ and the joy the world offers.
Worldly joys are always based on circumstances. We feel joyful only when our lives are going well. If you got a great job, a big house, tight relationships, entertainment at your disposal, comfort and security, good health, then we're joyful.
But worldly joys are also temporary, and often fleeting with diminishing returns. That includes career and financial success, luxury entertainment experiences, and even our relationships and our health: We need constant renewal of all these things to even sustain the same level of joy as before.
These worldly joys aren’t bad in themselves but if you’re looking to get complete satisfaction and joy in life from it, you’ll be sorely disappointed at best, or utterly devastated at worst.
But the good news is that there is such a joy that exists, which can completely satisfy.
It’s a joy that only Jesus can give us, and more than that, he tells us in His Word, that we can fully experience it today.
