Dr. David Livingstone, the Scottish missionary explorer, awakened the world to the horror of the Arab slave trade, which he called a "monster of iniquity brooding over Africa." By publicizing the evil of slavery, Livingstone worked effectively to see it abolished.
For every 20,000 slaves captured and exported, he estimated 100,000 Africans were killed, wounded, or died of disease on the slave trails. He wrote: "The many skeletons we have seen along the paths of the wilderness attest the awful sacrifice of human life that must be attributed to this trade in hell."
Today, there are millions who are enslaved by sins. The Lord Jesus has awakened us all to that fact. He wants us to be His witnesses to share the Good News of salvation and liberation from sins through His completed work on the Cross.
