There was the good, waiting to be gained, and here was the man, but he had no man to stand for him between the need and the supply. A few years ago a great famine raged just back from the coast of China. There were millions of Chinese families who were in want and hundreds of thousands died of starvation because there was not bread enough to feed them. Little children lay crying at the breasts of dead mothers by the roadsides. At that very hour the wheat was piled up at railroad stations in Argentina as high as church spires. There was grain enough to feed the starving millions in China. Here was the supply and there was the need, but where were the men? God had not men enough on whom to float the supply across to meet the need. What is true of outward need is true of inward need as well. There is never a want where there is not an adequate supply. No little child on this earth need go hungry because God has not put enough in this world to feed it. No human heart need go starved because there is not enough love to meet its wants. There is all the food and all the love that humanity needs. But there are lacking the men who for God will bring the supply to the demand. The human need in the world can be met by the supply only through men who will fill up the gap. God can do it only as men lend themselves to Him. That is why, through all the years, the call of God has been for volunteers. For every unique, external, individual call that has been given to men, you can find a million calls that have been just the answer of men to the great call of God for volunteers. And God surely values the volunteer above the conscript. Isaiah did not wait for any special coercive call. “Also I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then said I, Here am I; send me.” That call was enough to cover him, and he answered it. There is so much work to be done that God cannot go marching through the world looking for individuals, performing new miracles by which each individual is to be thaumaturgically led up to his particular work. God’s general way has been to picture before the eyes of His sons the work to be done and to wait for their hearts to leap in response, as Isaiah’s leaped: “Lord, let me have a share in this work ‘Here am I; send me.’”
