Mark 13:10
This verse means several things, but the main point makes a lot of sense in the context. Before the end of the story, all the world will have been reached with the gospel of Christ. This goes back to the previous verse. The mission of the Great Commission is not simply one of conversion. We don’t preach only to those likely to believe. We preach to everyone. Why? Well, because not only does God want people to be saved, but he wants the lost to hear the truth, even if they never get saved.
I believe that this means that before the end every governmental grouping of people will have been reached with the gospel. The question is exactly how small of a group that could entail, and that answer is not entirely clear. I believe it safe to say that any straggling pockets of persons that have not heard will only have not heard because they are in very closed groups that don’t explore much.
Besides all this, in Revelation, the gospel will be proclaimed by an angel before it is all said and done. We find this in Revelation 14:6-7. So, ultimately the idea is that no ethnic group on earth could claim that they were ‘missed’ in the Great Commission.
Heavenly Father, thank you for allowing us to be part of your work. You have blessed us and made us able to minster. It is the joy of our lives to be able to share your truth with others. Thank you! In the name of the Lord Jesus Christ I pray and praise you, Amen.
