Paul.

Paul was a missionary.
Paul preached the gospel all over the early world.
Paul was not held back by lack of things.
If Paul did not have a camel, Paul walked. 
Paul was not stopped by threat of death,
threat of bodily harm,
threat of imprinsonmetn.
Paul was not stopped by
beatings,
verbal assaults,
threats,
jailings,
presecution,
hunger,
sickness,
exhaustion,
ship wrecks or
snake bites.
I feel challenged today.
