As for who God is:
Well, God is love
(Who had shown his love towards us when we were yet sinners, Christ (God) died for us).
1. God is Omni-Temporal (Eternal).
2. God is Omniscient (All knowing).
3. God is Omnipotent
(Sovereign and all powerful; Doctrine of Immanence is implied in this).
4. God is Omni-Righteous
(God is love. He is always loving, Good, Morally upright always; Even in His anger He loves).
5. God is Omni-Present
(Capable of Being Present in all locations).
6. God is Self Sufficient
(Aseity; Eternally: God does not need anything or anyone to survive or to be happy or complete).
7. God is Immutable
(Unchanging; God's Spirit in essence and being will never change, nor will His good character).
8. God is Holy
(God is Holy and divine; This means He is perfect, pure, without spot, blameless, and sacred).
9. God is Spirit
(Transcendent and beyond the physical universe).
10. God is Triune
(The Lord our God is one God who exists eternally as three persons: The Father, the Word, and the Holy Ghost).
11. God is Light
(God can put forth Light from His being).
12. God is Infinite
(As in relation to essence of His divine being or Spirit: God is not subject to physical limitations (like man)). (For with God, nothing is impossible).
These are qualities of God, but it doesn't answer the question, what do you mean by God? You asked me if I believe Jesus is God and I asked you to define what you mean by God. Some of these qualities do pertain to Jesus some don't.
"1. God is Omni-Temporal (Eternal)."
Yes, He's eternal.
2. God is Omniscient (All knowing)."
No, He himself said that He did not know the hour of His return.
32 But
of that day and that hour knoweth no man, no, not the angels which are in heaven,
neither the Son, but the Father. (Mar 13:32 KJV)
"3. God is Omnipotent
(Sovereign and all powerful; Doctrine of Immanence is implied in this)."
NO, He Himself said the power came from the Father.
25 For he must reign, till he hath put all enemies under his feet.
26 The last enemy that shall be destroyed is death.
27 For he hath put all things under his feet. But when he saith all things are put under him,
it is manifest that he is excepted, which did put all things under him.
(1Co 15:25-27 KJV)
"4. God is Omni-Righteous
(God is love. He is always loving, Good, Morally upright always; Even in His anger He loves)."
Yes, He is righteous.
5. God is Omni-Present (Capable of Being Present in all locations)"
No, Scripture says He was here and He went there. If He traveled from here to there then it's obvious He isn't everywhere.
14 And Jesus returned in the power of the Spirit into Galilee: and there went out a fame of him through all the region round about.
15 And he taught in their synagogues, being glorified of all.
16 And
he came to Nazareth, where he had been brought up: and, as his custom was,
he went into the synagogue on the sabbath day, and stood up for to read. (Luk 4:14-16 KJV)
6. God is Self Sufficient
(Aseity; Eternally: God does not need anything or anyone to survive or to be happy or complete).
No, Paul said the Father alone has immorality.
13 I give thee charge in the sight of God, who quickeneth all things, and before Christ Jesus, who before Pontius Pilate witnessed a good confession; {confession: or, profession}
14 That thou keep this commandment without spot, unrebukeable, until
the appearing of our Lord Jesus Christ:
15
Which in his times he shall shew, who is the blessed and only Potentate, the King of kings, and Lord of lords;
16
Who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom be honour and power everlasting. Amen. (1Ti 6:13-16 KJV)
7. God is Immutable
(Unchanging; God's Spirit in essence and being will never change, nor will His good character).
No, Scripture says He was in the form of God and emptied Himself taking on the form of a servant, that's change.
7 but emptied Himself, taking the form of a bond-servant, and
being made in the likeness of men. (Phi 2:7 NAS)
8. God is Holy
(God is Holy and divine; This means He is perfect, pure, without spot, blameless, and sacred).
Yes He is Holy.
9. God is Spirit
(Transcendent and beyond the physical universe).
No, He Himself say a spirit does not have flesh and bone as you see I have.
39 Behold my hands and my feet, that it is I myself: handle me, and see; for
a spirit hath not flesh and bones, as ye see me have. (Luk 24:39 KJV)
10. God is Triune
(The Lord our God is one God who exists eternally as three persons: The Father, the Word, and the Holy Ghost).
No, one being is not three beings.
28 Ye have heard how I said unto you, I go away, and come again unto you. If ye loved me, ye would rejoice, because I said, I go unto the Father: for
my Father is greater than I. (Joh 14:28 KJV)
11. God is Light
(God can put forth Light from His being).
Yes, He is light
12. God is Infinite
(As in relation to essence of His divine being or Spirit: God is not subject to physical limitations (like man)). (For with God, nothing is impossible).
No, Jesus Himself said that He couldn't do some things.
19 Then answered Jesus and said unto them, Verily, verily, I say unto you,
The Son can do nothing of himself, but what he seeth the Father do: for what things soever he doeth, these also doeth the Son likewise. (Joh 5:19 KJV)
