The title “the Lord” is used only for God. This is seen in both the Old and New Testament.
And God spake unto Moses, and said unto him, I am the Lord: - Exo 6:2
… the angel of the Lord appeareth to Joseph in a dream … - Matt 2:13
Consider that John the Baptist was “to prepare the way of the Lord” (Matt 3:3, Matt 11:10, Mark 1:2-3, Luke 1:76, Luke 3:4, Luke 7:27). Of course, this refers to the Lord Jesus Christ, who then must be God. This was predicted in the Old Testament in Isa 40:3. It is also predicted in Mal 3:1, where in addition to that, the Lord will come to his temple.
Jesus Christ is called “the Lord” many times.
For unto you is born this day in the city of David a Saviour, which is Christ the Lord. - Luke 2:11

That is over 200 times where Christ is called the Lord, all which prove Christ is God.
The following titles also show that Christ is God: the Lord Jesus, the Lord Jesus Christ, the Lord Christ, Christ Jesus the Lord, and our Lord Jesus Christ. These occur over 110 times. Again all these prove Christ is God.
In fact, every time that Jesus Christ is called “Lord”, it indicates that Christ is God since there is only one Lord, who indeed is God. And this occurs about 500 times in the New Testament.
It is established fact that Jesus Christ is the Son of God. For example:
The beginning of the gospel of Jesus Christ, the Son of God; - Mark 1:1
But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name. - John 20:31
And Philip said, If thou believest with all thine heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God. - Acts 8:37
Christ is called the Son or the Son of God 120 times in the New Testament. From the following passage and others, the title the Son of God declares that Jesus Christ is God.
… said also that God was his Father, making himself equal with God. - John 5:14.
There are several passages from the Old Testament which reveal the Son of God, Jesus Christ. For example, in Isa 53, begins with the following verses:
1 Who hath believed our report? and to whom is the arm of the Lord revealed? 2 For he shall grow up before him as a tender plant …- Isa 53:1-2
Now from 1 Sam 2:31, an arm is used to describe a son. So the arm of the Lord is the Son of the Lord, that is, the Son of God. And this is an actual man as revealed by the phrase “he shall grow up” in verse 2. Later in that chapter, Christ is described as dying for our sins and rising from the dead.
This is predicted in Isa 9:14, where it says, “a virgin shall conceive, and bear a son”. This is the virgin conception and birth of the Son of God, Jesus Christ. Since God is His Father, a man could not be His father. This was revealed in Gen 3:15, where God said “her seed”, not their seed. It is also revealed later in Gen 3:20, where Eve is “the mother of all living” but Adam is not the father of all living.
John the Baptist said of Jesus Christ, “Behold the Lamb of God, that taketh away the sin of the world”. This is a fulfillment of what Abraham said to Isaac, “God will provide himself a lamb” (Gen 22:8). In fact, this is the very location where Christ would be crucified, since you can see Calvary from where the temple was built (Gen 22:1, 2 Chron 3:1). Thus God Himself would be the Lamb of God who would be crucified for the sins of the world. This was promised in Gen 3:15 and is further expounded on in Isa 53, where the Son of God would be crucified for all sins and rise from the dead. Again this proves Christ is God.
In the New Testament, on many occasions, Jesus Christ forgave sins. But from scripture, only God can forgive sins (Mark 2:5-11). So again, Jesus Christ is God.
The Lord said unto my Lord
The following verse shows that Jesus is the Word made flesh. Thus Jesus Christ is fully God and fully man.
And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth. - John 1:14
