Cast thy bread upon the waters: for thou shalt find it after many days. (Ecclesiastes 11:1)
We must not expect to see an immediate reward for all the good we do; nor must we always confine our efforts to places and persons which seem likely to yield us a recompense for our labors. The Egyptian casts his seed upon the waters of the Nile, where it might seem a sheer waste of corn. But in due time the flood subsides, the rice or other grain sinks into the fertile mud, and rapidly a harvest is produced. Let us today do good to the unthankful and the evil. Let us teach the careless and the obstinate. Unlikely waters may cover hopeful soil. Nowhere shall our labor be in vain in the Lord.
It is ours to cast our bread upon the waters; it remains with God to fulfill the promise “Thou shalt find it.” He will not let His promise fail. His good word which we have spoken shall live, shall be found, shall be found by us, Perhaps not just yet, but some day we shall reap what we have sown. We must exercise our patience, or perhaps the Lord may exercise it. “After many days,” says the Scripture, and in many instances those days run into months and years, and yet the Word stands true. God’s promise will keep; let us mind that we keep the precept and keep it this day.
