I am sure we all could make a long list of reasons for the lack joy in our lives. That list would most certainly include sickness, stress, setbacks, suffering, struggles of life, sin in our own lives, and that of the world around us. The biggest mistake we often make is to think the happiness and joy are one and the same. Happiness depends on the circumstances of one’s life. If my life happens to happen the way I want it to happen, then I am happy. "Joy to the world! To understanding this Christmas Joy, you most understand the keys... Watch out to the teaching "Great Joy". Advent from the Gospel of Luke by Olaoluwa Popoola. Great joy is God’s Christmas gift to us. The birth of Christ was a fulfillment of numerous prophecies about the Messiah. Shalom
