Joy comes from the expectation or possession of some good. Spiritual joy comes from the expectation of possessing the ultimate good, God, and not just for a time but for all eternity.
An example of someone living this spiritual joy was St. Teresa of Avila. She once remarked, "May God protect me from gloomy saints." She knew that truly spiritual people had this authentic joy welling up from within.
Joy is also one of the 12 fruits or effects of the Holy Spirit dwelling within the soul. In Galatians 5:22–23, St. Paul lists these 12 effects of possessing God here and now: "But the fruit of the Spirit is charity, joy, peace, patience, benignity, goodness, longanimity, mildness, faith, modesty, continency, chastity. Against such, there is no law."
