Are you feeling like you need to leave the secure and familiar for the sake of Jesus? This is also part of following Jesus for He told us; “As the Father has sent me, even so I am sending you.”
Paul certainly felt this and modeled a missionary lifestyle: I make it my ambition to preach the gospel, not where Christ has already been named, lest I build on someone else’s foundation, but as it is written,”Those who have never been told of him will see, and those who have never heard will understand.” -Romans 15:19-20
