Well, since you asked. . .
Let's begin with John's gospel:
John opens his Gospel with the "Word," which in Greek philosophy was the First Cause, the great Intelligence and Reason behind the Universe, which John declares is the recently despised and crucified man, Jesus of Nazareth, who is the eternal Logos, source of all wisdom and power, and who became flesh in order to reveal God to us.
In the beginning was the Word--the Word is eternal (see Jn 17:5, 24; 1Jn 1:1-3),
which Word was with God--distinct from the Father, personality (personhood)
and which word was God-deity of the Word who is distinct from the Father,
through him--male personhood,
all things were made--creator (Col 1:13-17),
in him was life--all life in creation is in and through him (Col 1:17),
the life was the light of men--the Word revealing,
the Word became flesh (Jn 1:14)--incarnation,
which incarnation reveals the Word to be God's Son, the only begotten of the Father (Jn 1:14),
to which Heb 1:3-4 testifies.
Then what do you conclude from what Jesus states about himself?
He often refers to three, Father, Holy Spirit, and Son (himself) in his many claims about himself; e.g.,
he came down from heaven (Jn 3:13, 6:38, 42, 62, 8:58, 17:5, 24; 1Jn 1:1-4),
from glory (John 17:5, John 16:28) where he was before (John 6:62),
"before Abraham was, I AM" (John 8:58), and
was sent by God (Jn 5:36-40, 10:36, 13:3, 16:28),
possessing all authority (power) in heaven and earth (Mt 26:64, 28:18; Lk 10:22; Jn 13:3, 13)
to die as a ransom for the sins of many (Mt 20:28, 26:28; Jn 10:11)
with power to forgive sin (Mt 9:2-6),
to conquer Satan (Jn 12:31; Lk 10:18; Mk 1:23-26, 5:6-13),
to speak for God (Jn 7:16, 8:25-28, 12:44-45, 49-50, 14:10; Lk 9:35, 10:16),
and to judge all mankind (Jn 5:22, 27, 8:26, 12:48; Mt 25:31-33),
as the exclusive (barring all others) way to God (Jn 14:6),
the source of all truth and life (Jn 1:4, 14:6, 5:25-26, 6:40),
the decisive factor in the eternal destiny of every man (Jn 3:18-19, 36; 5:24, 6:40, 8:24-25),
equal with God--doing what God does (Jn 5:18-19, 8:19, 12:44-45, 14:7-9, 16:15, 17:10),
--as the Father works, so the Son works (miracles) - (Jn 5:17),
--as the Father gives life, so the Son gives life (Jn 5:21),
--as the Father is Judge, so the Son is Judge (Jn 5:22),
--as the Father is to be honored, so the Son is to be honored (Jn 5:23),
--as the Father has life in himself, so the Son has life in himself (Jn 5:26)
--as the Father sends with authority and power, so the Son sends with authority and power (Jn 20:21)
--as the Father makes law, so the Son makes law (Mt 5:24-47, 12:7-8, 19:9, 21:23-27,ch 23, Lk 6:5)
--as the Father confers the kingdom, so the Son confers the kingdom (Lk 22:29),
empowering the apostle to speak for him, as well as for God (Lk 10:16; Jn 13:20),
to recall and understand all things correctly (Jn 14:26, 16:13-15; Lk 24:48-49), and
speaking exactly what God told him to say when he made these claims about himself (Jn 12:49).
Jesus is saying in these claims that he is no less than God. And this is the way the Jews understood him (Mk 2:3-7; Jn 6:41-42, 10:30-33, 5:18, 8:58-59, 19:7), which is why they killed him.
