A story from the life of missionaries Robert and Mary Moffat illustrates this truth. For 10 years this couple labored faithfully in Bechuanaland (now called Botswana) without one ray of encouragement to brighten their way. They could not report a single convert. Finally the directors of their mission board began to question the wisdom of continuing the work. The thought of leaving their post, however, brought great grief to this devoted couple, for they felt sure that God was in their labors, and that they would see people turn to Christ in due season. They stayed; and for a year or two longer, darkness reigned. Then one day a friend in England sent word to the Moffats that she wanted to mail them a gift and asked what they would like. Trusting that in time the Lord would bless their work, Mrs. Moffat replied, “Send us a communion set; I am sure it will soon be needed.” God honored that dear woman’s faith. The Holy Spirit moved upon the hearts of the villagers, and soon a little group of six converts was united to form the first Christian church in that land. The communion set from England was delayed in the mail; but on the very day before the first commemoration of the Lord’s super in Bechuanaland, the set arrived.
