In the Bible “creation” is an alpha and omega theme: in the Book of Genesis we learn about the original creation when “God created the heaven and earth” and in the Book of Revelation we see the glorified creation (re-creation) when the one who “sat upon the throne said, Behold, I make all things new” (Revelation 21:5).
The Lord Jesus Christ is the Second Adam who by way of obedience and righteousness will make new all the things that the First Adam corrupted by way of sin and rebellion: “For as in Adam all die, even so in Christ shall all be made alive” (1 Corinthians 15:22); “For if by one man’s offence [Adam’s] death reigned by one; much more they which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ” (Romans 5:17).
“Creation” is an alpha and omega theme because all of Scripture speaks of the Creator-Christ: Christ is the “Alpha” Creator, “In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by him; and without him was not any thing made that was made. In him was life; and the life was the light of men” (John 1:1-4), and Christ is the “Omega” Creator, “And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea. And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband. . . . And he that sat upon the throne said, Behold, I make all things new. And he said unto me, Write for these words are true and faithful. And he said unto me, It is done. I am the Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely. He that overcometh shall inherit all things; I will be his God, and he shall be my son” (Revelation 21:1-2, 5-7).
