"I am the Alpha and the Omega" [Note: These are the first and last letters of the Greek alphabet, and indicate "the beginning and the end" See 21:6], says the Lord God Almighty, who is [in the present], and who was [in the past] and who will come [in the future].
Then He said to me, "These things have already happened. [Note: These words express the certainty of what has been predicted in this book, even though not all the events had actually taken place yet]. I am the Alpha and the Omega [See note at 1:8], the beginning and the end. I will give the person who is [spiritually] thirsty [a drink] from the spring of water of life without his having to pay for it.
