As someone who's involved in the ministry of Every Home Crusade, supplying Gospels and other Christian Literature through the world I found the following estimates very interesting.
Estimated Languages in the World - 6912
Estimated Languages without a Bible Translation - 2251
Within these 2251 Languages without Scripture there are an Estimate of 193Million people.
This is a possible 193 Million people who have no opportunity to read the Scriptures in their own language. Astonishing!
