Son of God

Why will Jesus “be called the Son of God” (Luke 1:35)?
Instead of being conceived between Mary and a man, Jesus will enter the womb of Mary when “the Holy Spirit” comes to her “and the power of the Most High” overshadows her: “therefore also, the Holy One to be born will be called the Son of God” (Luke 1:35).

Why did the angel say, “therefore also” (Luke 1:35), Jesus will be called the Son of God?
Jesus' resurrection will be the other reason why He will be “declared the Son of God with power according to the Spirit of Holiness by the resurrection from the dead” (Romans 1:4).

Did Jesus' existence begin inside Mary's womb?
No, “in the beginning,” before the world was created, Jesus already “was God” (John 1:1), who is eternal: “from everlasting to everlasting You are God” (Psalm 90:2). Jesus entered humanity through Mary's womb, where He became a human being to live a sinless life and then give His life to pay the death penalty due for our sins, but He never stopped being God. During His time on earth, Jesus was neither only human nor only God nor half human and half God. From Mary's womb until His ascension to heaven, Jesus was fully human, as demonstrated by the fact that He felt “thirst” (John 19:28), got “hungry” (Matthew 4:2, 21:18) and “tired” (John 4:6), and fully God, as demonstrated by His power over His creation - And having awakened, He rebuked the wind and said to the sea, “Silence! Be still!” And the wind ceased, and there was a great calm (Mark 4:39) - and His power over death (see Resurrection of Jesus).

Was Jesus ever called “Son of God” before He entered humanity?
No. Some English translations of Daniel 3:25 quote the pagan King Nebuchadnezzar of Babylon as saying that one of the four figures he sees walking around in the fire is “like the Son of God,” but this is a mistranslation since in the original language, the word translated “God” is plural, not singular, and there is no “the” before “Son,” so the correct translation of this phrase is “like a son of the gods,” meaning an “angel,” as Nebuchadnezzar himself explained just three verses later in Daniel 3:28. Therefore, while the fourth figure Nebuchadnezzar saw in the fire could have been Jesus, he didn't identify Him as the “Son of God.”

What was Jesus called until He entered humanity?
“God” (Isaiah 9:6), “Lord” (Psalm 110:1), “Word” (John 1:1), “Son of Man” (Daniel 7:13), etc. Also see “burning torch” in Genesis 15:17.
