God the Son is found in scripture by logical necessity.
John 1:1 says the "Word" (Logos) was both with God, thus another Person, and was God.
John 1:14 says "And the Word became flesh, and dwelt among us; and we saw His glory, glory as of the [monogenes] from the Father, full of grace and truth." The Greek word monogenes when used to describe an aspect of God in the flesh, says He is unique , and the reason is God in the flesh is uniquely divine, God incarnate.
John 3:16 says, "“For God so loved the world, that He gave His [monogenes] Son, so that everyone who believes in Him will not perish, but have eternal life.
Thus the Second Person of the Trinity, Logos became a "monogenes" from God when He became flesh, and this "mongenes" refers to God's Son.
