Martyrdom
According to Todd M. Johnson and the World Christian Encyclopedia, from AD33 to 1914 24 million Christians died for their faith. Just since AD1915 an additional 45 million Christians died for their faith in Christ. This means that more Christians were martyred in the 1900s than all the previous centuries combined.
Reaching the Whole World
What is a People Group?
When God gives you a task, it is infinitely important that you know the definition of the task. God has promised to reach all the nations of the earth and commissioned us as His ambassadors in that work. In order to be good stewards of this mission we must have a firm grip on the extent of the task, which, in the work of world missions, brings us to look closely at the terms that the Bible uses for the task. Namely, what does it mean to reach the nations?

If the command given by Jesus is to make disciples of all nations (or ethnic groups), then common sense would tell us our job is to find those nations (ethnic groups) that have not been discipled (taught to be followers of Christ). The vast majority of these unreached people live in an area of the world nicknamed the "10/40 window."
