1 Sam. 20:23

“May the Lord make us keep our promises to each other, for He has witnessed them.”

Those at home never know just how much the missionaries overseas truly rely on their promises to pray. Even when they are sent out to work with a national church, missionaries still have problems of loneliness and culture shock. But when they go to an unreached people, they enter into situations where they are invading Satan’s previously unchallenged territory. He will attack them in many ways beyond the expected culture shock. If those at home who promised to pray for them do not keep their promise, some of these missionaries may experience severe defeat in their personal lives or public ministries. But earnest, continual prayer can make the difference.
