Faith comes by hearing the Word of God which is spoken by messengers who are sent.
God’s design is that those who have heard and believed His message should carry it and send it to those who have not. (Romans 10)
It is only natural that those who love God should love their neighbor enough to tell them all about Him.
There are 131,000 Evangelical Christians for each of the 2500 unreached people groups. The main obstacle is knowing and acting upon our earthly commission for the eternal benefit of those who have not heard.
Faith comes by hearing God’s Word.
This is true both of the faith of those who have not yet heard the Gospel and those who might tell them.
We need to tell the potential messengers and those who would send them to tell remote people.
We need to walk by faith so that others might believe God.
