God has blessed Africa with many missionaries in the past like David Livingston, Mary Slessor and many others, and also missionary in this present time. I have a friend from the Philippines who is a medical doctor who is serving in the country of Congo, and he has done many surgeries successfully.
But just because a person is an American missionary “doctor” does not automatically give any African parents to trust them with your children. I understand that because of the poverty in Africa, we are quick to take the bait of free medical care, foods, and others. And also illiteracy also contributes to the factor.
