The Apostle Paul, one of the first Missionaries in the Church, did risk everything and did end up executed for his work. But he also wrote back to the Churches to instruct them, and the one thing he did not tell every Christian was to become Missionaries in foreign lands. Not everyone can be or should be Missionaries.
The spreading of the Gospel is not something you have to leave your home town to do; there are many people around you that need the Gospel as well.
There is a great saying about the Gospel:
Spread the message of Christ constantly. When necessary, use words.
But you are correct. Way too many Christians ignore the Great Commission of Jesus, which is to spread the Gospel to all men.
Yes, I agreed with you before you typed that. I clearly mentioned my respect for those who have risked it all, for their faith.
They are the true believers.
