"For my people have committed two evils; they have forsaken me the fountain of living waters, and hewed them out cisterns, broken cisterns, that can hold no water." Jer. 2:13
This is a verse that Piper quotes a lot... The "cisterns" are the things of this world....things that we are tempted to believe hold that cool, refreshing water...but they are BROKEN...
There is no true satisfaction in anything that is worldly. Our only true satisfaction is in Christ...the true, "fountain of LIVING WATERS"!
