God is a person called: Thee, Thou, Thine, Thy

God is never called (you), nor (your)!
In the book, men call (King James Bible), the words for 2 or more people are always (you, your).
The words for one person are always: (Thee, Thou, Thine, Thy).
God is one person and he is called by all these words (thee, thou, thy, thine).
We can find all these words for God being one person in this one precept of Exodus 15 line 7:

Exodus 15:
[6] Thy right hand, O LORD, is become glorious in power: thy right hand, O LORD, hath dashed in pieces the enemy.
[7] And in the greatness of thine excellency thou hast overthrown them that rose up against thee: thou sentest forth thy wrath, which consumed them as stubble.

God is a Spirit. The word (a) is singular because God is a person and not persons.

John 4:
[24] God is a Spirit: and they that worship him must worship him in spirit and in truth.

Interpretations belong to God (read Genesis 40 line 8); and the interpretation of these 3 names we read in 1John 5 line 7 is given by Job who worshipped God in spirit and in truth when he gave a great witness, and testimony, and warning in Job 13 lines 7 through 10):

1John 5:7 For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.

Job understood (these three are the three names of one person); and we know with certainty Job worshipped Jesus in spirit and in truth:

Job 13:
[7] Will ye speak wickedly for God? and talk deceitfully for him?
[8] Will ye accept his person? will ye contend for God?
[9] Is it good that he should search you out? or as one man mocketh another, do ye so mock him?
[10] He will surely reprove you, if ye do secretly accept persons.

Job 42:
[7] And it was so, that after the LORD had spoken these words unto Job, the LORD said to Eliphaz the Temanite, My wrath is kindled against thee, and against thy two friends: for ye have not spoken of me the thing that is right, as my servant Job hath.
