When he saw the lost people he told his disciples to ask the Lord of the harvest to send workers into the harvest field because the harvest was plentiful and the workers are few.
Maybe I can't personally go into these nations and share the gospel message, but God can and I know that he will if we ask Him to.
One of my favorite scriptures to pray for the lost people in the world is taken from Romans 10:11-15 "As the scripture says, 'Anyone who trusts in him will never be put to shame. For there is no difference between Jew and Gentile - the same Lord is Lord of all and richly blesses all who call on him, for, 'Everyone who calls on the name of the Lord will be saved.'
How then can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them? And how can they preach unless they are sent? As it is written, "How beautiful are the feet of those who bring good news."
