Don't let
  any root
  of bitterness
Springing up in me
Send out
  stealthy runners
  to invade
Another's growth in Christ.

Rather let
  a well
  of living water
Springing up in me
Overflow
  uncontained, splashing
  down upon
Another's arid ground.
 - Nancy Spiegelberg

If anyone is thirsty. Let him come to me and drink. Whosoever believes in me, as the Scripture has said, streams of living water will flow from within him.
John 7:37b-39 NIV
(Words of the Lord Jesus Christ)
