Here, in my judgment, is one of the subtlest temptations that faces any Christian in any era: If we are not careful, we can get diverted here from what Christ has called us to do in this present age. This happened in Thessalonica not twenty years after Jesus died, and Saint Paul met the issue head on. Some of the people there got so caught up in expecting and predicting the imminent return of the Lord that they had ceased to do any work and degenerated into idle busybodies who prattled only about the future (2 Thessalonians 3:11). Paul rebuked this tendency to let an over-interest in "the last things" divert us from faithfulness to "the first things."
There is an old story about a warrior who was struck one day by a poisonous arrow. This man happened to be a speculative sort of person, so as he lay on the ground, he mused to himself: "I wonder what kind of wood this arrow is made of? What sort of birds, do you suppose, the feathers come from? I wonder what type of man shot this arrow - tall or short, dark or light." His comrades, who saw his plight, could bear it no longer, but cried out in frustration: "For God's sake, man! Stop speculating and pull out the arrow!"
Consider the story of one young man. He was often sick as a baby. He was always small, puny some would say. As a youth he was always frail and delicate. He was not able to play sports with the other boys his age. Eventually he entered the ministry. But his health was so fragile, he was unable to serve his growing congregation.
Amazingly, he did not dwell on his troubles. In fact, his spirit soared. His only real complaint was the poor quality of the hymns of his day. He felt they did not convey hope and joy. Someone challenged him to write better ones. He did. He wrote over 600 hymns, most of them hymns of praise.
When his health collapsed completely in 1748, he left one of the most remarkable collection of hymns the world has ever known. His name was Isaac Watts. In a few weeks we will be singing one of his most famous hymns, "Joy to the World!" Isaac Watts discovered joy in his life because he knew that God would never desert him. He was able to live his life with all sorts of health problems feeling close to God and Jesus. He had joy deep in his heart.
