As we have therefore opportunity, let us do good to all men, especially to them who are of the household of faith.
See that well on the mountain-side — a small, rude, rocky cup full of crystal water, and that tiny rill flowing through a breach in its brim. The vessel is so diminutive that it could not contain a supply of water for a single family in a single day. But, ever getting through secret channels, and ever giving by an open overflow, day and night, summer and winter, from year to year, it discharges in the aggregate a volume to which its own capacity bears no appreciable proportion. The flow from that diminutive cup might, in a drought or war, become life to all the inhabitants of a city. It is thus that a Christian, if he is full of mercy and good fruits, is a greater blessing to the world than either himself or his neighbours deem. Let no disciple of Christ either think himself excused, or permit himself to be discouraged from doing good, because his talents and opportunities are few. Your capacity is small, it is true, but if you are in Christ it is the capacity of a well. Although it does not contain much at any moment, so as to attract attention to you for your gifts, it will give forth a great deal in a lifetime, and many will be refreshed.
(W. Arnot, M. A.)
