Scripture refers to 3 as God All of these are God and each of these are God:
The Father is God
2Pe_1:17 For he received from God the Father honour and glory, when there came such a voice to him from the excellent glory, This is my beloved Son, in whom I am well pleased.
The Son is God
Psa 78:35 And they remembered that God was their rock, and the high God their redeemer.
1Co 10:2 And were all baptized unto Moses in the cloud and in the sea;
1Co 10:3 And did all eat the same spiritual meat;
1Co 10:4 And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ.
Jesus is God because the OT says Israel's Rock was God and Christ was that same Rock.
Holy Spirit is God
Act 5:1 But a certain man named Ananias, with Sapphira his wife, sold a possession,
Act 5:2 And kept back part of the price, his wife also being privy to it, and brought a certain part, and laid it at the apostles' feet.
Act 5:3 But Peter said, Ananias, why hath Satan filled thine heart to lie to the Holy Ghost, and to keep back part of the price of the land?
Act 5:4 Whiles it remained, was it not thine own? and after it was sold, was it not in thine own power? why hast thou conceived this thing in thine heart? thou hast not lied unto men, but unto God.
Here lying to the Holy Spirit is called lying to God.
Mat 4:23 And Jesus went about all Galilee, teaching in their synagogues, and preaching the gospel of the kingdom, and healing all manner of sickness and all manner of disease among the people.
This is the first appearance of the word in the bible. The word is:
G2098
εὐαγγέλιον
euaggelion
yoo-ang-ghel'-ee-on
From the same as G2097; a good message, that is, the gospel: - gospel.
Total KJV occurrences: 77
It is written as the gospel of the Kingdom, the gospel of God, the gospel of Jesus, the gospel of peace etc. It is good news about something, usually related to righteousness and the future for righteous people. In short, it is usually about how Jesus died for our sins so we can repent and be forgiven and be granted immortality in the eternal kingdom of God ie: being saved.
