THERE are some Christians, who once visited the sick, taught in the Sunday school, or in other ways rendered their Lord a little service, but now that they are advanced in years and knowledge, they seem to think that their working days are over. Like an old horse in my neighbor’s field, which has not done a day’s work for the last five years, they seem to be pensioned off. Better wear out than rust out, fellow Christian. It is a miserable thing for a man to be like that old horse eating, eating from morning to night, —and doing nothing.
