Progress!

"It took 18 centuries for dedicated believers to grow from 0% of the world's population to 2.5% in 1900, only 70 years to grow from 2.5% to 5% in 1970, and just the last 30 years to grow from 5% to 11.2% of the world population. Now for the first time in history there is one believer for every nine people worldwide who aren't believers...we're talking about Bible-reading, Bible-believing stream of Christianity." (Ralph D. Winter and Bruce A. Koch/Perspectives)
