And he said to me: ‘They have come to pass! I am the Alpha and the Omega, the beginning and the end.’”​—Revelation 21:5, 6a.

Why, so certain are these promises of Jehovah that he speaks as though they were already fulfilled: “They have come to pass!” Is not Jehovah “the Alpha and the Omega . . . , the One who is and who was and who is coming, the Almighty”? (Revelation 1:8) Indeed he is! He himself declares: “I am the first and I am the last, and besides me there is no God.” (Isaiah 44:6) As such, he can inspire prophecies and fulfill them in every detail. How faith strengthening!
