Muslims - Visions
Some places on Earth are hard to reach for the gospel, because of their hostile environments, but that doesn't stop Jesus from reaching out to them in different ways.
Check out this YouTube video about how Jesus reaches out to Muslims with visions.
I strongly believe that everyone will have a chance to hear the gospel in the end time - there shall be no excuse.
And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
- Matthew 24:14 (KJV)
