He is the King of Glory !
Ps 24:7-10
7 Lift up your heads, O ye gates; and be ye lift up, ye everlasting doors; and the King of glory shall come in.
8 Who is this King of glory? The Lord strong and mighty, the Lord mighty in battle.
9 Lift up your heads, O ye gates; even lift them up, ye everlasting doors; and the King of glory shall come in.
10 Who is this King of glory? The Lord of hosts, he is the King of glory. Selah.
Jesus is God because He is the King of Glory, Notice here Vs 10
10 Who is this King of glory? The Lord of hosts, he is the King of glory. Selah.
The Lord of Hosts ! We know there is only One Lord of Hosts and lets read Isa 6:1-3
1In the year that king Uzziah died I saw also the Lord sitting upon a throne, high and lifted up, and his train filled the temple.
2 Above it stood the seraphims: each one had six wings; with twain he covered his face, and with twain he covered his feet, and with twain he did fly.
3 And one cried unto another, and said, Holy, holy, holy, is the Lord of hosts: the whole earth is full of his glory.
Now its interesting in this blessed vision Isaiah sees the Lord sitting on a Throne, which denotes a King, and in this vs 3 the Person sitting upon the Throne is Identified as the Lord of Hosts as in Ps 24:10, and it says that the whole Earth is full of His Glory, again this harmonizes with what is stated in Ps 24:10
10 Who is this King of glory? The Lord of hosts, he is the King of glory. Selah.
Now who exactly is the Lord of Hosts in Isaiah 6:3 ? Lets read the scripture in Jn 12:37-41
37 But though he had done so many miracles before them, yet they believed not on him:
38 That the saying of Esaias the prophet might be fulfilled, which he spake, Lord, who hath believed our report? and to whom hath the arm of the Lord been revealed?
39 Therefore they could not believe, because that Esaias said again,
40 He hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them.
41 These things said Esaias, when he saw his glory, and spake of him.
Now here John inspired by the Spirit is identifying the One Isaiah saw in Isa 6:3 as the Lord Jesus Christ who performed miracles amongst the jews and they believed not on Him ! When Isaiah spoke of His Glory; So Jesus Christ is the Lord of Hosts, the King of Glory.
In Isa 6:1, Isaish said The King was High and Lifted Up Isa 6:1
In the year that king Uzziah died I saw also the Lord sitting upon a throne, high and lifted up, and his train filled the temple.
That word lifted up is the hebrew nasa' and means:
Exalted to be lifted up, be exalted. Hence the Lord Jesus Christ after His Death we know was exalted to Highest Glory per Phil 2:8-9
8 And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.
9 Wherefore God also hath highly exalted him, and given him a name which is above every name:
However, this Exalted state of Glory Christ had before His Incarnation Per Jn 17:5
5 And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was.
Thats who Isaiah saw in Isaiah 6:1-3 as the exalted Lord of Hosts, King of Glory as Per Ps 24:7-10 !
To deny this scripture testimony of the Deity of Jesus Christ is simply unbelief !
