The three masons

It’s said that in the Middle Ages, three stonemasons were working hard on a construction site, below the hot sun, when a visitor arrived and asked what they were doing.
The first mason, working hard with sweat running down his forehead, said complaining: “I’m cutting this rock.”
The second mason, although less annoyed, answered after a deep breath: “I’m building this parapet.”
The third mason answered with a radiant face: “I’m building this beautiful cathedral which will glorify God for centuries to come.”
The same work, three different visions. One was concerned with the here and now; the next with the near future; and the last was concerned with eternity.
Where is your vision?
