=For when one saith, I am of Paul; and another, I am of Apollos; are ye not men? What then is Apollos? and what is Paul? Ministers through whom ye believed; and each as the Lord gave to him. I planted, Apollos watered; but God gave the increase. So then neither is he that planteth anything, neither he that watereth; but God that giveth the increase. Now he that planteth and he that watereth are one: but each shall receive his own reward according to his own labor. For we are God's fellow-workers: ye are God's husbandry, God's building.--I Cor. 3:4-9.= One of the profoundest motives that can grip man's heart is the conviction that he is a fellow-worker with the Divine. To feel that there is a great Cause, on behalf of which God himself is concerned, and in the furtherance of which we can be God's instruments and confederates, is the most exhilarating outlook on life conceivable. Even people who deny God try to get this motive for themselves. One such man hopes for the success of his favorite causes in "the tendency of the universe"; another talks about "the nature of things taking sides." _But nothing save personality has moral tendencies, and only persons take sides in moral issues._ If the guidance of the world is personal, then, and then only, can we rejoice with confidence in a great Ally, who has moral purposes and who has committed to us part of his work. This was the Master's motive when he said, "My Father worketh even until now, and I work" (John 5:17). But one clearly sees that such an inspiring consciousness of cooperation with the Eternal depended on the certainty with which the Master called the Eternal by a personal name--Father. When men like Livingstone have gone out in sacrificial adventure for the saving of men they have not banked on the "tendency of the universe," nor trusted in any abstract "nature of things taking sides"; they have been servants of a personal God, under orders from him, and they have counted on personal guidance in the service of a cause whose issue was safe in God's hands. _O God, we pray Thee for those who come after us, for our children, and the children of our friends, and for all the young lives that are marching up from the gates of birth, pure and eager, with the morning sunshine on their faces. We remember with a pang that these will live in the world we are making for them. We are wasting the resources of the earth in our headlong greed, and they will suffer want. We are building sunless houses and joyless cities for our profit, and they must dwell therein. We are making the burden heavy and the pace of work pitiless, and they will fall wan and sobbing by the wayside. We are poisoning the air of our land by our lies and our uncleanness, and they will breathe it._
