Joy is supposed to be part of what defines a Christian, yet if we're honest, we often fail to exude it. One reason is because we have a misunderstanding of what God the Father is like. Part of the Good News of Christmas is that Jesus came to earth to reveal the Father to us. Through Jesus we learn God is full of joy and this joy is poured out for us to tap into. Our joy will be evident only to the degree in which we can trust this.
