The second man, you say? I agree. Jesus is a man not God).
Wrong. There are literally dozens of lords in the Bible. This includes the Lord God and the Lord Jesus. Two lords. See Psalm 110:1.
The very next verse (16) states what all of Scripture, every Epistle states, there is one God, the Father. Why do you suppose in v16, the text changes the Father in reference to who God is to referencing who the lord is in referencing Jesus other than the author meant something different in using these different words?
This is akin to the US having only one POTUS. Yet, for every person, there is also (for them) one Governor, which is analogous to that very same verse changing the word referring to one to lord. This is hierarchy, which is also stated many times in Scripture between God and his Anointed. See Jesus submitting to the will of his God. You do know that Jesus has a God, right?
NOTE: There is no Lord Holy Spirit in Scripture. What do you make of that and this supposed person not even having a name?
I realize there are earthly lords and kings, and angelic principalities too, who are all lesser than THE Lord of lords, and King of kings. The name of Jesus is above every name. These are some further scriptures that speak to His divinity: "In the beginning was the Word and the Word was with God, and the Word was God. By Him all things were made...." "Before Abraham was, I AM!" "God was manifest in the flesh." "Show us the Father.....I have been with you all this time and have you not know me? If you have seen me you have seen the Father." "Thomas answered and said unto Him, my Lord and my God"
Col 1:15-19
Who is the image of the invisible God, the firstborn of every creature:
For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him:
And
he is before all things, and by him all things consist.
And
he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence.
For it pleased the Father that in him should all fulness dwell;
Such inconceivable and beautiful humility that the Lord God lowered Himself to come and live in the weak flesh of mortal man and willingly subject Himself to cruel hands so that we could be saved. We worship Jesus and praise Him, and give Him thanks, and call upon His name. No way could we do that with any mere human being, but only God, otherwise we are all idolators. All power and authority in heaven and earth was given to Him. Are we sufficient to understand these things fully how they could be? No, we only understand in part.....but we believe even if we don't fully understand. Concerning the coming of Jesus, it says in the Psalm, "A body thou hast prepared for me" Even we mere humans are something more than just our physical body, no?
I am not sure if I understand this fully, but consider that His Spirit, is HIS Spirit, not separate from Him, just like our human spirit is our spirit and is the essence of who we are....the Spirit of Christ and the Spirit of God are termed interchangeably in scripture because it is one and the same Spirit.
And yes, God was Jesus' God because as the previous scripture I posted explains, being found in the form of a man, Jesus voluntarily and humbly subjected Himself to the Father and became His servant. He was both God and man....son of God and son of man.
