See what you can do for Jesus Christ in the shop. See whether you can serve your Master in that little Bible class of which you are a member. Rest assured that no missionary ardour really burns within that man who does not love the souls of those who live in the same house and dwell in the same neighbourhood.
Give me that man for a missionary of whom it is said that, when he took a lodging in a house, all the other inhabitants were brought to God within six months; or one who was a son whose father was unconverted, but who gave the Lord no rest until he saw his parent saved; or one who was a tradesman who, while he was pushing his business earnestly, always found time to be an evangelist.
That is the man who will maintain missionary fervour alive at home, and that is the man who will help to promote missionary effort abroad.
