Cast thy bread upon the waters: for thou shalt find it after many days. Give a portion to seven, and also to eight; for thou knowest not what evil shall be upon the earth. If the clouds be full of rain, they empty themselves upon the earth… – Ecclesiastes 11:1-3

What says Solomon? “Cast thy bread upon the waters: for thou shalt find it after many days.” Go, my brothers and sisters, and find out the most unlikely people, and begin to work for God with them. Now, try, if you can, to pick out the worst street in your neighbourhood, and visit from house to house, and if there is a man or woman more given up than another, make that person the object of your prayers and of your holy endeavours. Cast your bread upon the waters; then it will be seen that you are trusting God, not trusting the soil, nor trusting the seed.

“Give a portion to seven, and also to eight.” Talk of Christ to everybody you meet with. If God has not blessed you to one, try another; and if He has blessed you with one, try two others; and if He has blessed you to two others, try four others; and always keep on enlarging your seed-plot as your harvest comes in.

Learn this lesson: “If the clouds be full of rain, they empty themselves upon the earth;” and say to yourself, “If God has made me full of grace, I will go and pour it out to others. I know the joy of being saved, if I have had fellowship with Him, I will make a point of being more industrious than ever, because God has been unusually gracious to me. My fulness shall be helpful to others. I will empty myself for the good of others, even as the clouds pour down the rain upon the earth.” Beloved, sow in the morning, sow in the evening, sow at night, sow all day long, for you can never tell what God will bless. ~ C.H. Spurgeon
