Revelation 22:16-17 (KJV)
16 I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star.
17 And the Spirit and the bride say, Come. And let him that heareth say, Come. And let him that is athirst come. And whosoever will, let him take the water of life freely.
Jesus says come and you will never thirst again. He offers living waters for all those that will believe in Him as Lord and Savior.
