"He that watereth shall be watered also himself" (Prov. 11:25).
"For... with what measure ye mete, it shall be measured to you again" (Matt. 7:2).
It will generally be found that those persons who are perpetually complaining of want of love in others are utterly failing in love themselves; and, on the other hand, those who are really walking in love will tell you that they receive a thousand times more than they deserve. Let us remember that the best way to get water out of a dry pump is to pour a little water in. You may work at the handle until you are tired, and then go away fretful and impatient, complaining of that horrible pump; whereas, if you would just pour a little water in, you would get in return a gushing stream to satisfy your utmost desire.
