ONE GOD: THE FATHER, THE SON, AND THE HOLY SPIRIT!

EVIDENCE OF THE TRIUNE GOD IN THE OLD TESTAMENT

In the following verses, note that "God" in the Hebrew is  אֱלֹהִים ('elohiym), a plural masculine noun; also notice the pronouns in Genesis 1:26-27 are also plural:

Genesis 1:1 - "In the beginning God...."
Genesis 1:26-27 - "And God said, Let Us make man in Our image, after Our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.  So God created man in His own image, in the image of God created He him; male and female created He them."
Deuteronomy 6:4-5 - "Hear, O Israel: The LORD our God is one LORD:  And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might."

EVIDENCE OF THE TRIUNE GOD IN THE NEW TESTAMENT

Matthew 3:16-17 - "And Jesus, when He was baptized, went up straightway out of the water: and, lo, the heavens were opened unto Him, and He saw the Spirit of God descending like a dove, and lighting upon Him:  and lo a voice from heaven, saying, This is My beloved Son, in Whom I am well pleased."
Matthew 28:19-20 - "Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:  teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world.  Amen."
John 14:16-17, 26 - "And I (Jesus) will pray the Father, and He shall give you another Comforter, that He may abide with you forever; even the Spirit of truth; Whom the world cannot receive, because it seeth Him not, neither knoweth Him:  but ye know Him; for He dwelleth with you, and shall be in you....But the Comforter, which is the Holy Ghost, Whom the Father will send in My name (Jesus), He shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you."
Ephesians 2:18 - "For through Him (Jesus) we both have access by one Spirit unto the Father."
1 Timothy 3:15-16 - "But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and ground of the truth.  And without controversy great is the mystery of godliness:  God was manifest in the flesh (Jesus) , justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory."
1John 5:5-7  - "Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?  This is He that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth.  For there are three that bear record in heaven, the Father, the Word (Jesus), and the Holy Ghost: and these three are one."

WHEN YOU TRUST THAT JESUS DIED FOR YOUR SINS ACCORDING TO THE SCRIPTURES, THAT HE WAS BURIED, AND THAT THE FATHER RAISED HIM FROM THE DEAD, AS THE SCRIPTURES HAD SAID HE WOULD, YOU ARE FILLED WITH THE SPIRIT!  (John 14:16-20; 1 Corinthians 15:3-4)
