One of the things that will mark God’s dwelling place is joy. This is more than happiness. Joy is a sense of satisfaction that causes us to be overflowing with life. A joyful person is a satisfied person. That is one reason why God tells us not to try to get life from the things of the world, for joy only resides in Him. As the saying goes: happiness is based upon happenings, but joy is based upon Jesus.

Splendor and majesty are before him; strength and joy are in his dwelling place.
– 1 Chronicles 16:27 (NIV)
