Matthew 28:19-20 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
At a time when thousands of people were dying each year of rabies, Louis Pasteur, pioneer of immunology, was working on a vaccine. Just as he was about to begin experimenting on himself, a 9-year-old boy, Joseph Meister, was bitten by a rabid dog. The boy's mother begged Pasteur to experiment on her son. Pasteur injected Joseph for ten days-- and he lived. Decades later, of all the things Pasteur could have had etched on his headstone, he asked for three words: "JOSEPH MEISTER LIVED".
We are also called to save lives...and yes, even to takes risks to do so. Our greatest legacy will be those who live eternally because of our efforts. Thousands of people die each year never having heard the name of Yeshua (Jesus). Yet there are so many ways to reach them. We ought to risk a little time, money, or effort in that direction for their sake.
