We have had the privilege of growing up in a country where anyone at any time can learn about Jesus, but this is not the reality of a huge proportion of the world. 
In Romans 15:21, Paul quotes, ‘Those who were not told about him will see, and those who have not heard will understand.’ And this is our desire, that these people, who know so little of Jesus and have never had the opportunity to, will hear the gospel and be saved.
