"He chose twelve." Probably this was because there were twelve tribes of Israel, and the number was to be continued. One evangelist says that he sent them out two and two. Why by two and two? With all the world to evangelize, would it not have been better if they had gone out one by one? Then they would have reached twice as many points. Was it not a waste of force, of power, to send two to the same place? No doubt Jesus had reasons. It would have been lonely for one man to go by himself. If there were two, one would keep the other company. There was opposition to the gospel in those days, and it would have been hard for one to endure persecution alone. The handclasp of a brother would make the heart braver and stronger. We do not know how much we owe to our companionships, how they strengthen us, how often we would fail and sink down without them. One of the finest definitions of happiness in literature is that given by Oliver Wendell Holmes. "Happiness," said the Autocrat, "is four feet on the fender." When his beloved wife was gone, and an old friend came in to condole with him, he said, shaking his gray head, "Only two feet on the fender now." Congenial companionship is wonderfully inspiring. Aloneness is pain. You cannot kindle a fire with one coal. A log will not burn alone. But put two coals or two logs side by side, and the fire kindles and blazes and burns hotly. Jesus yoked his apostles in twos that mutual friendship might inspire them both. There was another reason for mating the Twelve. Each of them was only a fragment of a man--not one of them was full-rounded, a complete man, strong at every point. Each had a strength of his own, with a corresponding weakness. Then Jesus yoked them together so that each two made one good man. The hasty, impetuous, self-confident Peter needed the counterbalancing of the cautious, conservative Andrew. Thomas the doubter was matched by Matthew the strong believer. It was not an accidental grouping by which the Twelve fell into six parts. Jesus knew what was in man; and he yoked these men together in a way which brought out the best that was in each of them, and by thus blending their lives, turned their very faults and weaknesses into beauty and strength. He did not try to make them all alike. He made no effort to have Peter grow quiet and gentle like John, or Thomas become an enthusiastic, unquestioning believer like Matthew, He sought for each man's personality, and developed that. He knew that to try to recast Peter's tremendous energy into staidness and caution would only rob him of what was best in his nature. He found room in his apostle family for as many different types of temperament as there were men, setting the frailties of one over against the excessive virtues of the other.
