This salutation in the last of the seven church epistles in Revelation contains the last of four occurrences of the distinctive phrase, "the beginning of the creation." The glorified Christ here assumes this as one of His divine names. Note that even God's work of creation, long since completed (Genesis 2:1-3), had a beginning, and that beginning was Christ. "In the beginning was the Word, . . . All things were made by him" (John 1:1, 3).
The first two occurrences of this phrase also come from the lips of Christ. "From the beginning of the creation God made them male and female" (Mark 10:6). This assertion by the Creator, Jesus Christ (quoting Genesis 1:27), makes it unambiguously certain that Adam and Eve were created at the beginning of creation, not after the earth had already existed for 4.5 billion years. God also wrote this plainly on the tables of the law (Exodus 20:8-11). Those evangelicals who accept the geological ages evidently reject this clear statement of the creation's Creator!
Then Christ also referred to the end-times in the context of the beginning-times. "In those days shall be affliction, such as was not from the beginning of the creation which God created unto this time, neither shall be" (Mark 13:19).
The phrase is also used in Peter's very important prophecy concerning the scoffers of the end-times who will argue (in willful ignorance) that "all things continue as they were from the beginning of the creation" (2 Peter 3:3-4), thereby denying that there ever was a real creation or real Creator and thus rejecting Christ Himself. But He is also the "true witness" and the "Amen," and such denials will only be "unto their own destruction" (2 Peter 3:16). HMM
