In the parable of the Lost Sheep the shepherd leaves the 99 sheep to seek out the one that is lost. He uses all his resources to find the lost one. But the global church does the opposite! The vast majority of Christian resources are used to tend the flock and little is used to seek the lost. Over 95% of all missionaries work among already reached peoples. Only one cent out of every dollar of Christian resources goes to reaching unreached peoples.
Pray for the needs of Frontier People Groups with virtually no followers of Jesus living among them as their needs are even greater than the Unreached People Groups.
