Has Jesus always existed? John 3:16 "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life." In the Greek the same word is used for begotten in Hebrews 11:17 and it means unique. "μονογενῆ (monogenē): Often translated as "only begotten," it strictly means "one-of-a-kind" or "unique." https://search.brave.com/searchq=greek+John+3%3A16&conversation=09aaf8200162969fde56e53b938ed916ce43 and https://godrules.net/library/strongs2b/gre3439.htm In other words, there is no one like him and no one else could take his place. "By faith Abraham, when he was tried, offered up Isaac: and he that had received the promises offered up his only begotten son," https://www.bible.com/bible/1/HEB.11.KJV Abraham not only had Ishmael and Isaac, he also had other sons as given in Genesis 25:1 "Then again Abraham took a wife, and her name was Keturah. 2 And she bare him Zimran, and Jokshan, and Medan, and Midian, and Ishbak, and Shuah. 9 And his sons Isaac and Ishmael buried him in the cave of Machpelah, in the field of Ephron the son of Zohar the Hittite, which is before Mamre;" https://www.bible.com/bible/1/GEN.25.KJV Isaac was the son of promise, the one with whom the covenant was made. Jesus was the one who came because of the covenant was made back in Genesis 3:15 "and I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel." https://www.bible.com/bible/1/GEN.3.KJV In John 14:15 Jesus said, “If ye love me, keep my commandments.” https://www.bible.com/bible/1/JHN.14.KJV Who gave the commandments in Exodus 20? Exodus 20:1 “And God spake all these words, saying, 2 I am the LORD thy God, which have brought thee out of the land of Egypt, out of the house of bondage." https://www.bible.com/bible/1/EXO.20.KJV We compare Exodus 3:14 “And God said unto Moses, I AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you.” https://www.bible.com/bible/1/EXO.3.KJV with John 8:58 “Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am.” https://www.bible.com/bible/1/JHN.8.KJV and the picture becomes even more clear. In commentary on these verses EGW says in the book the Desire of Ages, “Silence fell upon the vast assembly. The name of God, given to Moses to express the idea of the eternal presence, had been claimed as His own by this Galilean Rabbi. He had announced Himself to be the self-existent One, He who had been promised to Israel, ‘whose goings forth have been from of old, from the days of eternity’. Micah 5:2,” margin. DA 469.5 https://egwwritings.org/read?panels=p130.2295&index=0 “Jehovah, the eternal, self-existent, uncreated One, Himself the Source and Sustainer of all, is alone entitled to supreme reverence and worship.” PP 305.4 https://egwwritings.org/read?panels=p84.1344&index=0 (see John 1:1 “In the beginning was the Word, and the Word was with God, and the Word was God. 2 The same was in the beginning with God. 3 All things were made by him; and without him was not any thing made that was made.”) https://www.bible.com/bible/1/JHN.1.KJV “Before Abraham was, I am.” Christ is the pre-existent, self-existent Son of God. The message He gave to Moses to give to the children of Israel was, “Thus shalt thou say unto the children of Israel, I AM hath sent me unto you.” The prophet Micah writes of Him, “But thou, Bethlehem Ephratah, tho thou be little among the thousands of Judah, yet out of Thee shall He come forth unto Me that is to be ruler in Israel; whose goings forth have been from of old, from everlasting.” ST August 29, 1900, par. 13 https://egwwritings.org/readpanels=p820.16966&index=0 Jesus has always existed and is divine and one with the Father. Here are other blogs about Jesus’ divinity. https://iodtiger.blogspot.com/2018/07/examining-each-text-more-on-jesusgod.html and https://iodtiger.blogspot.com/2013/03/jesusgod.html
The Spirit of Prophecy is also clear on this subject. The following are quotes from EGW writings. When Satan rebelled in heaven, "They (God the Father and God the Son) clearly set forth that Jesus was the Son of God, existing with him before the angels were created; and that he had ever stood at the right hand of God, and his mild, loving authority had not heretofore been questioned;" 1SP 19.1 https://egwwritings.org/readpanels=p141.63&index=0 "The Lord Jesus Christ, the divine Son of God, existed from eternity, a distinct person, yet one with the Father." RH April 5, 1906, par. 7. https://egwwritings.org/read?panels=p146.102&index=0 "He was the only-begotten Son of God, who was one with the Father from the beginning." 9 LtMs, Ms 92, 1894, par. 1 https://egwwritings.org/read?panels=p14059.5123006&index=0 "When man’s redemption was to be worked out, God gave the commandment that the sword should awake against His only begotten Son, who had been one with Him from eternity." 18LtMs, Ms 76, 1903, par. 25 https://egwwritings.org/readpanels=p14068.9640038&index=0
