Revelation 21:5-6

5And the one sitting on the throne said, “Look, I am making everything new!” And then he said to me, “Write this down, for what I tell you is trustworthy and true.”

6And he also said, “It is finished! I am the Alpha and the Omega—the Beginning and the End. To all who are thirsty I will give freely from the springs of the water of life.
