All of us can experience moments of great joy because in His goodness God allows us to taste on earth the joys of the world to come. However, moments of joy, no matter how wonderful, will never satisfy the human heart. What we long for is a permanent state of happiness but that is unattainable here. So what must we do? Like desert travellers we must go forward from one oasis to another, with the conviction that God has a homeland prepared for us at the end of our journey. This conviction will make it possible for us to travel onwards with an ache in our heart and an unquestionable longing in our soul.
