WHO IS THE LORD GOD?

Lord is a title with various meanings. It can denote a prince or a feudal superior (especially a feudal tenant who holds directly from the king, i.e., a baron). The title today is mostly used in connection with the peerage of the United Kingdom or its predecessor countries, although some users of the title do not themselves hold peerages, and use it 'by courtesy'. The title may also be used in conjunction with others to denote a superior holder of an otherwise generic title, in such combinations as "Lord Mayor" or "Lord Chief Justice". The title is primarily taken by men, while women will usually take the title 'lady'. However, this is not universal, as the Lord of Mann and female Lord Mayors are examples of women who are styled 'lord'.

NOTE:  we see quite plainly that 'the Lord' is a title, NOT a name. Also note that the title 'lord' is subject to a king... The Creator of all things is NOT subject to anyone!

In religious contexts Lord can also refer to various different gods or deities.
In Hindu theology, The Lord or Svayam Bhagavan refers to the concept of absolute representation of the monotheistic God.
Other religious uses of the word Lord include:
Ba'al, or Baal, is a Northwest Semitic title meaning 'lord', used for various gods and local spirit-deities... References to Baal in the Hebrew Bible, such as the prophet Elijah's confrontation with Baal's priests, usually correspond to local gods rather than to Hadad.
Bel meaning 'Lord' is a common title of the Babylonian deity Marduk.

So not only is the this title used by many religions, it is a Hebrew title for the false god Ba'al whom the scriptures (over 50 times) define as detestable to Yahweh!
Yeremiyah 19:5  “...and have built the high places of Baʽal, to burn their sons with fire for burnt offerings to Baʽal, which I did not command or speak, nor did it come into My heart.”
Most people would also recognise the name Ba'al as a synonym for Satan.
See what Yahweh has to say about the substitution of His Name for Ba'al:
“Till when shall it be in the heart of the prophets? – the prophets of falsehood and prophets of the deceit of their own heart, who try to make My people forget My Name by their dreams which everyone relates to his neighbour, as their fathers forgot My Name for Baʽal (The Lord).”  (Yeremiyah 23:26,27)

According to the Oxford Dictionary of English, the etymology of the word can be traced back to the Old English word 'hlaford' which originated from 'hlafweard' meaning 'bread keeper' or 'loaf-ward', reflecting the Germanic tribal custom of a chieftain providing food for his followers. Lady, the female equivalent, originates from a similar structure, believed to have originally meant 'loaf-kneader'.

NOTE: Some claim that 'the name of the Lord' is an English term for our Creator, yet it's origin isn't even English!And now the title of 'the Lord' is described as a barbarian bread provider...
Wikipedia Again:

People have often used the term 'lord' in religious contexts, where, The Lord refers to God in Judaism or Islam, or to God, Jesus, or the Holy Spirit in Christianity. In the Anglican Church there are also Lord Bishops. In many Christian Bibles (such as the King James Version), the Hebrew name YHWH (the Tetragrammaton) is rendered LORD (all caps) or LORD (small caps). This usage follows the Jewish practice of substituting the spoken Hebrew word 'Adonai' (translated as 'Lord') for YHWH when read aloud. Following practice in Hebrew, the Septuagint mainly used the Greek word Kyrios (meaning 'lord') to translate YHWH. As this was the Old Testament of the Early Church, the Christian practice of translating the divine name as 'Lord' derives directly from it.

This is just one example of the FACT that the one and only Name of our Creator has been REMOVED from our Scriptures and CHANGED to a title originating from pagan deities.
The Word says this:
Deuteronomy 4:2  “Do not add to the Word which I command you, and do not take away from it, so as to guard the commands of Yahweh your Elohim which I am commanding you.”

If a believer were to come into an assembly saying, "Ba'al is my saviour", or quoting from Scripture saying, "Thus says Ba'al"; that so-called believer would get a sharp short talking to and most likely be escorted to the door if they continued to do so! There is NO DIFFERENCE calling Yahweh "The Lord" or "Ba'al"...

SHOCKED YET? Just to show the severity of this travesty; look at these Scriptures where “Ba'al” has been translated into English:

Judges 2:13  “So they forsook Yahweh and served the Lord and the Ashtoreths. And the displeasure of Yahweh burned against Yisra’ĕl.”

Yeremiyah 12:16 “And it shall be, if they learn well the ways of My people, to swear by My Name, ‘As Yahweh lives,’ as they taught My people to swear by the Lord, then they shall be established in the midst of My people.”

1 Kings 18:21 “And Ěliyahu came to all the people, and said, “How long would you keep hopping between two opinions? If Yahweh is Elohim, follow Him; and if the Lord, follow him.” But the people answered him not a word.”

1 Kings 22:52-53  “and did evil in the eyes of Yahweh... and served the Lord and bowed himself to it, and provoked Yahweh Elohim of Yisra’ĕl, according to all that his father had done.”

Most people acknowledge the fact that "Beelzebub" is another name for Satan, yet may not realise that it is two Hebrew words: Ba'al -Zebub, meaning "lord of flies" or "lord of heavenlies" !
Wake up and smell the sulphur! THE LORD = BA'AL = SATAN
If you continue to call the Creator (Yahweh) of all things by the title of 'the Lord', then you are quite simply continuing in the sins of ancient Israel whereby they were 'divorced' by Yahweh.

The earliest written form of the Germanic word god comes from the 6th century Christian Codex Argenteus. The English word itself is derived from the Proto-Germanic *gudan. Most linguists agree that the reconstructed Proto-Indo-European form *ghu-to-m was based on the root *ghau(e)-, which meant either "to call" or "to invoke". The Germanic words for god were originally neuter - applying to both genders - but during the process of the Christianization of the Germanic peoples from their indigenous Germanic paganism, the word became a masculine syntactic form.
The capitalized form God was first used in Ulfilas's Gothic translation of the New Testament, to represent the Greek Theos. In the English language, the capitalization continues to represent a distinction between monotheistic "God" and "gods" in polytheism. In spite of significant differences between religions such as Christianity, Islam, Hinduism, the Baha'i­ Faith, and Judaism, the term "God" remains an English translation common to all.

To summarise how the Germanic term for a Pagan deity became a title of the One True Creator, it appears as though the Catholic Institution is once again responsible for the "Universalisation" of all beliefs into their one world religion.

Studying further back in history, it turns out that "God" dates back much further and is recorded in Scripture that God (Gawd) was an ancient name for the god of luck!
Leah; one of the wives of Ya'aqob actually named one of her sons after this deity...
This is how many Bibles translate why Leah named her son Gad:
Genesis 30:11  “Then Leah said, "What good fortune!" So she named him Gad.” (NIV, RSV, NASB, NLT, etc.)
From Strong's Hebrew: H1410 - גּד   gâd   gawd
Remember both Leah and her sister Rachel were raised by a father who worshipped false gods and were responsible for naming the sons. Notice when Rachel left her father's house with the family:
Genesis 31:19  “And when Laḇan had gone to shear his sheep, Rahĕl stole the house idols that were her father’s.”

Here's what Wikipedia has to say about Gad (Gawd/God):

Gad was the name of the pan-Semitic god of fortune, and is attested in ancient records of Aram and Arabia. Gad is also mentioned by the Book of Isaiah (Isaiah 65:11 - some translations simply call him (the god of) Fortune), as having been worshipped by a number of Hebrews during the babylonian captivity.

Here's what Yahweh's word from the Law given to Mosheh says about the names of other 'gods':
Exodus 23:13  “And in all that I have said to you take heed. And make no mention of the name of other mighty ones, let it not be heard from your mouth.”

And again Yahweh warned Yehoshua before He brought Israel into the promised land:
Joshua 23:7  “... so as not to do in among these nations, these who remain among you. And make no mention of their mighty ones, nor swear by them, nor serve them nor bow down to them.”

And a third time from Dawid, the man after Yahweh's own heart:
Psalm 16:4  “The sorrows of those who run after another one are increased; I would not pour out their drink offerings of blood, nor take up their names on my lips.”


SUMMARY
Here's what you get when you put these two 'titles' together:
                                                 LORD GOD = BA'AL GAD
Ba'al Gad is mentioned several times in Scripture
Joshua 12:7  “And these are the sovereigns of the land which Yehoshua and the children of Yisra’ĕl smote beyond the Yardĕn, on the west, from Ba'al Gad in the Valley of Lebanon.”

Ba'al Gad in Strong's Hebrew
H1171  -  בּעל גּד   ba‛al gâd   bah'-al gawd
From H1168 and H1409; Baal of Fortune; Baal Gad, a place in Syria: - Baal-gad.
When you refer to Yahweh as the Lord God you are calling Him Ba'al of Fortune!
So the Scripture this study started with is in fact a LIE!
“Whosoever shall call on the Name of the Lord shall be saved.” (Acts 2:21)
We know that Yahweh is not a liar and His Word is Truth (John 17:17) and that the lying scribes have changed his Word. This Scripture is quotes from the First Covenant book of Yo'el (Joel) and because many scholars are admitting that the Renewed covenant was originally scripted in Hebrew and later into Greek (rendering the Name of the Almighty as "Kurios" - Greek for Lord) then the only way this Scripture can be fulfilled is to translate what it truly reads when quoted from Joel 2:32:
“Whosoever shall call on the Name of YAHWEH shall be delivered.”

Acts 17:30  “Truly, then, having overlooked these times of ignorance, Elohim now commands all men everywhere to repent.”

May Yahweh bless you as you seek to obey Him.
“Choose you this day whom ye will serve...but as for me and my house, we will serve YAHWEH.” (Yehoshua 24:15)
