Right now in the wold there are about 3,000,000,000,000 people who could walk for days and never find a church, a Christian, or a Bible. God's plan A is that Christians with the Good News of Jesus would go announce it, herald it across those lands. And God has no plan B.
"For 'everyone who calls on the name of the Lord will be saved.' How then will they call on him in whom they have not believed? And how are they to believe in him of whom they have never heard? And how are they to hear without someone preaching? And how are they to preach unless they are sent? As it is written, "How beautiful are the feet of those who preach the good news!" | Romans 10:13-15
