There is an old wisdom story that tells the tale of three masons building a cathedral. When asked what work they are doing the first replies that he is doing very heavy, backbreaking, difficult work which is killing him while the second replies that he is working hard to provide income for his family whom he loves very much, and the third replies that he is working as part of a team to build something beautiful that people will enjoy for centuries to come, and which will bring greater honor and glory to God.
What is the "moral" to the story?
There could be many interpretations and lessons a person could take away from it, but perhaps the most insightful is the idea that the meaning we make from the events and activities in our lives can make all the difference in the quality of the lives we experience and that other people experience through us.
The third mason will have a much richer, more satisfying, and fulfilling life, and the second will gain much satisfaction from his sense of achieving purpose, and the first will continue to be miserable finding no purpose or higher calling to explain to himself the point of his labors.
Jesus said that the Kingdom Of God is within you. It is in our own mind and heart that we find either heaven or hell.
