Comment: Our Lord is widely reputed to have said : " Go ye into all the world, and preach the gospel to every creature."

If I recall Sr. Dorothy's life, she went to Brazil after she retired from her life of ministry in the United States.  Following the call of the Spirit, she left her comfortable existence and removed to a far country where she took up the opportunity to accompany God's people, there, as they make their way.  

It was on that way that she met the powers of darkness, and had the opportunity to bear witness to the Light of Christ.

Any one of us can do this, where ever it is that we are, who ever it is that we are.
