I am the Alpha and Omega, the beginning and the end, the first and the last. (Rev. 22:13)

This dicitation is actual quotes that I have found in Scripture to highlight this claim.

Christ was with God in Creation: In the Beginning God created the heaven and the earth. (Gen. 1:1)

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 anything made that was made. (John 1:1-3)

And the Word was made flesh, and dwelt among us (and we beheld His glory, the glory as of the only begotten of the Father,) full of grace and truth. (John 1:14)

God who at sundry times and in divers manners spake in time past unto the fathers by the prophets. Hath in these last days spoken unto us by His Son, whom He hath appointed heir of all things, by whom also He made the worlds; Who being in the brightness of His glory, and the express image of His person, and upholding all things by the word of His power, when He had by Himself purged our sins, sat down on the Right Hand of the Majesty on high. (Heb. 1:1-3)

But unto the Son He saith, Thy throne, O God, is for ever and ever: a sceptre of righteousness is the sceptre of thy kingdom. Thou hast loved righteousness, and hated iniquity; therefore God, even Thy God, hath annointed Thee with the oil of gladness above Thy fellows.

And, Thou, Lord, in the beginning hast laid the foundation of the earth; and the heavens are the works of thine hands. (Heb. 1:8-10)

In whom we have redemption through His Blood, even the forgiveness of sins: Who is the image of the invisible God, the firstborn of every creature: For by Him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities or powers:* all things were created by Him, and for Him. And He is before all things, and by Him all things consist. (Col. 1:14-17)

* These are but some of the Names of the Angelic Hierarchy.

Christ Claimed Pre-existence:

Jesus said unto them, Verily, verily, I say unto you, before Abraham was, I AM. (John 8:58)

Jesus said unto them, If God were your Father, ye would love Me; for I proceedeth forth and came from God; neither came I of Myself, but He sent Me. (John 8:42)

And now O Father, glorify Thou Me with Thine own self with the glory which I had with Thee before the world was. (John 17:5) And God said unto Moses, "I AM THAT I AM." and He said, "this shalt thou say unto the children of Israel, 'I AM hath sent me unto you.'" (Exodus 3:14)
