I watched the 1988 Italian film Cinema Paradiso. The story was interesting, but the characters like most of us dwelt a little too much on the past. The past, whether happy or sad, is gone forever. Dwelling upon it can really impede one's spiritual progress. When I am enjoying the joy of knowing Jesus, the past becomes irrelevant. Jesus said it right: "No one who sets a hand to the plow and looks to what was left behind is fit for the kingdom of God." With Jesus, it's plowing ahead (following the Master) joyfully all the way. It's the healthiest outlook on life we can ever have.
