is God the Father.Jesus the Son.and the Holy Ghost ONE BEING?

well there is no verse which says that trinity exists, in bible.... the word TRINITY is not there in bible

Yea, your right the word trinity is not in the bible, but it says the Father, the Son, and the HolySpirit are one. They are 3 persons, yet one. You have to understand theology to understand trinity. God said let us make man in his own image. The us is the 3 yet one the Father, the Son, and the HolySpirit. You also have to understand what God was doing during certain times to understand his nature. When he provided something for someone, he was called Yahweh-Yireh or Jehovah-Jireh, or when he gave someone peace he was called Yahweh-Shalom, or Jehovah-Shalom. God is one God, but has many names. So, you have to understand his nature to understand him. He can be more than one place at one time, and can hear everything and everyone, because he is God. Jesus was sent on earth in the form of a human, but was still God. Jesus is the second person of the Godhead. That's how awesome God is. He can send himself to earth to live among his creation, us, humans to save us. So, yes the word trinity is not in the bible the the word us is, us mean 3 yet one. Father,Son,HolySpirit
