Martin Luther wrote from an intense personal experience when he addressed the topic of enduring trials and testing. Throughout his life, Luther experienced ill health, often severe. He had to deal with problems of the heart, kidney and bladder stones, ulcerated legs, devastating prostate troubles, migraine headaches and recurrent breathing difficulties.
However, Luther refused to see his illness as divine punishment but rather as a natural consequence of man's sinful state. It was to be countered with both prayer and medication but one relied ultimately on the will of God. Indeed, he felt God's presence and power more acutely in his sickness than in times
of greater vitality. After recovering from an illness so serious that his basic life signs were undetectable, Luther wrote the great hymn, "A Mighty Fortress Is Our God," in which he expressed his trust in God's victory over the devil's forces with these concluding words, "Though life be wrenched away, they cannot win the day. The kingdom is ours forever."
Also, take note of the following words from the great British preacher, Charles Spurgeon. He too dealt with poor health all his life, but especially in his last decade when he was nearly incapacitated. He writes, "I have suffered many times from severe sickness and frightful mental depression seeking almost to despair. Almost every year I've been laid aside for a season, for flesh and blood cannot bear the strain, at least such flesh and blood as mine. I believe, however, the affliction was necessary to me and has answered salutary ends. But I would, if it were God's will, escape from such frequent illness. That must be according to His will and not mine."
This is a frank admission of the pain that trials involve but, near the end of his life, Spurgeon also wrote this, "I venture to say that the greatest earthly blessing that God can give to any of us is health, with the possible exception of sickness. Sickness has frequently been of much greater use to the saints than has health."
