Yes, I agree God has many titles, and the title 'God' is just one title..........God has one name in reality, and that's his face, his light, the holy spirit of his command which is occupied by many souls who are the beautiful names of God but it's one word of light and showing the same truth. But he has many titles.
God has a perfect word by which he establishes believers by, that is his name, and it's the blessed tree of light.
Lord is another title, and so is King.
God does command His holy spirit - Psalms 104:30.
In the Bible we find God only has one personal name. It is represented by the Tetragrammaton YHWH.
In the King James Version the Tetragrammaton at Psalms 83:18 God's name is translated into English as Jehovah.
