A river reaches places which its source never knows. And Jesus said that, if we have received His fullness, “rivers of living water” will flow out of us, reaching in blessing even “to the end of the earth” (Acts 1:8) regardless of how small the visible effects of our lives may appear to be. We have nothing to do with the outflow— “This is the work of God, that you believe. . .” (John 6:29). God rarely allows a person to see how great a blessing he is to others.
