When we hear the term ' Lord God' do we think of Jesus or someone else?   I know that trinitarians think of someone else, but is this correct?   

Trinitarians say that God is three parts - Father, Son, Holy Spirit.   Is that because the Bible says so or because they struggle with the oneness of our Creator?   

Is Jesus Lord?   

And that every tongue should confess that Jesus Christ is Lord, to the glory of the Holy Spirit. - Phi 2:11 All humanity will speak in confession that Jesus is Lord and thus glorify the Father whose plan He fulfilled.      Who is the Father?     Holy Spirit.      It was the Holy Spirit that impregnated Mary.     It was the Holy Spirit that was in Jesus empowering Him to speak and do His will.      Jesus said if you have seen me you have seen the Father.      → Jesus is the body of the Holy Spirit.      → The Holy Spirit is the Spirit Of Christ Jesus.

Is Jesus the Father?   

Jesus says unto him, Have I been so long time with you, and yet have you not known me, Philip?     he that has seen me has seen the Father; and how say you then, Show us the Father? - Joh 14:9 Jesus states categorically who He is - the express image of the Father.     Joh 18:5

I and my Father are one. - Joh 10:30 yes!     The whole Truth comes out.      Jesus is the Lord (deity).      God (deity) is Jesus.      God (deity) is Spirit, hence He is the Holy Spirit.     The Holy Spirit made Himself a physical body and we call Him Jesus Mat 1:18 Luk 1:35.      It is through the body and soul of Jesus that the Holy Spirit expresses Himself in the Physical Realm.      There are not three.     There is One and His name is Jesus the express image of the Holy Spirit Heb 1:3.      → Do you know the name of the Father?      → Do you know the name of the Holy Spirit?      → Do you know the name of the Son?      There is One name of the One Creator and His name is Jesus.      It is in that name that we are saved.     It is in that name that we are healed.     It is in that name that all who reject Him will be judged.      Just as you are Spirit Soul And Body, so is our Lord in whose image we were created and by whose sacrifice we are redeemed.     Gen 1:26

Actually the Holy Spirit is the Father but the Holy Spirit is the Spirit Of Christ Jesus.   

Who is Lord God?   He is Christ Jesus who is the manifestation of our Heavenly (spiritual) Father, the Holy Spirit.   

Notice how the revelation of Truth about God comes clear as we read the verses below in which the term ' Lord God' is replaced with ' Lord Jesus'.
