Whoever brings blessing will be enriched, and one who
waters will himself be watered.
Proverbs 11:25 ESV
"This is a law of the divine administration, a law by which God designs that the streams of benefience shall be kept, like the waters of the great deep, in constant circulation, perpetually returning to their source. In the fulfilling of this law is the power of Christian missions." Testimonies for the Church vol.7, p.170 E.G.W.
