Magazine publisher J. I. Rodale, a zealous advocate of health foods, claimed at the age of 72 that he would live to be 100. The same week that his prediction appeared in The New York Times, he was being interviewed for a television program, again claiming that his bones were as strong as ever. Moments after making his boast, he died of a heart attack.

Dr. Stuart Berger, a nutritionist, claimed that he had the formula for living past the century mark. Although he had supposedly found the secret of youthfulness and had convinced many to follow his advice, he died in his sleep at the age of 40, grossly overweight.

Then there was author Jim Fixx, who advocated running to prevent coronary trouble. Yet at the age of 52 he died of a heart attack—yes, ironically, while running.

Common sense dictates that we ought to take every possible measure to keep ourselves healthy. But in the final analysis, each of us must pray, “I trust in You, O Lord . . . . My times are in Your hand” (Ps. 31:14-15).

Because any day, even today, may be our final day on earth, we need to be sure that we are ready to depart. Are you?
