Jesus and the Holy Spirit are in the Father and the Father is in Jesus and the Holy Spirit — they are One in thought, word and deed and substance— Spirit:
Many find it difficult to explain but The Blessed Trinity is the doctrine that states: God in three persons: the Father, the Son, and the Holy Spirit. The Trinity is a fundamental belief in most but not all denominations in Christianity.
The Trinity states that the Father, Son, and Holy Spirit are consubstantial, in other words — they share the same essence or substance— thus I simply define the Blessed Trinity is Three separate Persons — One Substance. Though they are individuals, they are Perfect in unity and Love, One in thought, word and deed and they are all Omniscient, all Omnipresent, and all Omnipotent. The only time The Blessed Trinity were NOT one— is when The Lord Jesus Christ emptied Himself of His Godhead and entered the Body that was prepared for Him — Philippians 2:7, Hebrews 10:5-7. A total separation took place at the Cross - Matthew 27:46 and Mark 15:34, Jesus is recorded as saying "Eli, Eli, lama sabachthani?" which translates to "My God, my God, why have you forsaken me?" while on the cross.
The Trinity reconciles the plurality of three divine beings with monotheism which is essential to the canon of the Word of God.
The Trinity is motivated by the Christian conviction that Jesus is equal with God but there is only one God.
Some versions of Monarchianism- which is a belief that God is one being, and that the Father, Son, and Holy Spirit are different manifestations of that one God. Monarchianism, It's also known as Sabellianism, Modalism, Modalistic Monarchianism, or modal monarchism are heresies that contradict the doctrine of the Trinity, But that violates Scripture and since Scripture cannot be violated (contradicted, added or taken away, these theory do not hold water.
Multiple attempts have been made to explain The Blessed Trinity, but none are completely accurate.
This also reveals that Jesus was the Lord God Jehovah (The Great I AM) in what we Christians call the Old Testament (which embodies more than one Covenant). Jesus was in the burning bush with Moses. He ate with Abraham and wrestled with Jacob and grabbed Ezekiel by the hair.
