Why there are three personalities in one God?
Why Christians worship Jehovah, Jesus and Holy Sprit as one God?
What is Trinity?

  1. Right from the beginning there were three personalities in Jehovah. Listen to his talk when he created man. Why the words "us’ and "our" which is plural in this verse. Genesis 1:26
  2. When God visited Abraham they were three not one. See the use of plural and singular intermingling to refer the same God. Genesis 18:1-18
  3. Prophets called Jehovah as Father for long. Isaiah 63:15-16, Isaiah 64:8
  4. It was the Holy Sprit who dwelt in prophets from the beginning. Isaiah 63:11-14
  5. Son who is Jesus is the first born of all, and he is the Lamb of God slain before the foundation of the world. God in his infinite wisdom was able to know the course of mankind and created Messiah even before the world and the heavenly hosts were created. John 17:24, Colossians 1:15-19, 1 Peter 1:18-20, Revelation 13:8
  6. Messiah the son was there even before David. Note the use of multiple entities in the Psalm like the Lord said to my Lord: "Sit at my right hand". Matthew 22:41-46, Psalm 110:1-2, Mark 12:35-37, Luke 20:41-44

So there is Father Son and the Holy Sprit in the single entity God which is described as Trinity. Since all three personalities are revealed now Christians worship the three by name and God as the single entity.
