For those who may reject some of the words of the Hebrew Scriptures (Old Testament), please take note that Jesus said he was the fulfillment of the Law and the Prophets -- all the teachings of God in Hebrew Scriptures -- and not "the smallest letter or stroke shall pass away from the Law, until all is accomplished," (Matthew 5:17, 18), and "Heaven and earth will disappear before the smallest letter of the Law does," (Luke 16:17).
Jesus frequently quoted from (often by saying, "It is written,") and referred to the Hebrew Scriptures. A small sampling:
Matthew --Matt. 9:13 quotes Hosea 6:6; Matt. 11:10 refers to Malachi 3:1; Matt. 12:3, 4 refers to David in 1 Samuel 21:6; Matt.13:14, 15 refers to Isaiah 6:10, Psalm 119:70, and Zechariah 7:11; Matt.15:4/Exodus 20:12, Deuteronomy 5:16, Exodus 21:17, and Leviticus 20:9; Matt. 19:4/Genesis 1:27, 5:2, and 2:24; Matt. 21:42/Psalm 118:22f; Matt. 26:24/"The Son of Man is to go, just as it is written of him; but woe to that man by whom the Son of Man is betrayed!"
Mark -- Mk. 4:12/Isaiah 6:9 and 43:8, Jeremiah 5:21, Ezekiel 12:2; Mk. 7:6, 7/Isaiah 29:13; Mk. 7:9, 10/Exodus 20:12, Deuteronomy 5:16, Exodus 21:17, and Leviticus 20:9; Mk. 9:12, 13/referring to prophecy that the Messiah must "suffer many things and be treated with contempt;" Mk. 10:6/Genesis 1:27 and 5:2; Mk. 12:29-30/Deutoronomy 6:4, 5; Mk. 12; 35-37/Psalm 110:1
Luke -- Lk. 4: 4/Deuteronomy 8:3; Lk. 4:8/Deuteronomy 6:13 and 10:20; Lk. 4:12/Deutoronomy 6:16 [Previous three verses in Luke 4 are instances where Jesus responds to Satan's temptations with quotes from Deuteronomy]; Lk. 4:18, 19/Jesus quoting Isaiah 61:1 and part of 2; Lk. 11:50, 51/referring to Abel's murder in Genesis 4:8 and to Zechariah's murder in 2 Chronicles 24:21; Lk. 13:35 and 19:38/Psalm 118:26; Lk. 16:29-31/referring to Moses and the Prophets; Lk. 19:46/Isaiah 56:7 and Jeremiah 7:11; Lk. 20:17/Psalm 118:22; Lk. 20:41-44/Psalm 110:1; Lk. 22:37/Isaiah 53:12; Lk. 24:27/"And beginning with Moses and with all the prophets, He explained to them the things concerning Himself in all the Scriptures."; Lk. 24:44-46/referring to a string of verses in the book of Psalm as follows, 2:7ff, 16:10, 22:1-8, 69:1-21, Chapter. 72, 110:1, 118:22f, "Now He said to them, 'These are My words which I spoke to you while I was still with you, that all things which are written about me in the Law of Moses and the Prophets and the Psalms must be fulfilled," (Lk. 24:44).
John -- Jn. 5:39-40/"You search the Scriptures because you think that in them you have eternal life; and it is these that bear witness of Me"; Jn. 8:56-58/Jesus refers to Abraham knowing Christ would come and states, "Truly, truly, I say to you, before Abraham was born, I am"; Jn. 12:14-16 [and Matt. 21: 4-5 and Lk. 19:29-32], Jesus asks the disciples to get a colt for him to ride on into Jerusalem/ Zechariah 9:9 tells us that Israel's King will come on a "donkey's colt."
He fulfilled over 300 the prophecies of the Messiah in Hebrew Scripture, such as:
Isaiah 9:1-7, part of which is quoted in Matthew 4:15-16 referring to Jesus as being the "great Light" which would come to the people "sitting in darkness"
Hosea 11:1, quoted in Matthew 2:15, speaking of God bringing His son back from Egypt
Isaiah 53, foretelling the suffering and sacrifice of Christ for sins
Luke 1: 33, 67-79; John 4:25, 26; and John 12:37-41, which refer to prophecies in Isaiah
John 19:33-37, the two men crucified with Jesus had their legs broken by the soldiers, "but coming to Jesus, when they saw that He was already dead, they did not break His legs; but one of the soldiers pierced His side with a spear." This connects to Exodus 12:46 and Numbers 9:12 referring to the command that the Passover lamb cannot have a broken bone; and it fulfills Psalm 34:20 which predicts that "He keeps all his bones; not one of them is broken," and to Zechariah 12:10, "..so that they will look on Me whom they have pierced."
Jesus fulfilled every law, living in perfect obedience to God the Father.
Thus, He was the very Lamb of the Hebrew Passover, the final sacrifice, "unblemished and spotless," (Isaiah 53:7; John 1:29; Hebrews 7:25-27; 1 Peter 1:19; Revelation 5:6). After his resurrection, Jesus told the disciples, "When I was with you before, I told you that everything written about me by Moses and the prophets and in the Psalms must all come true," (Luke 24:44).
His flesh was the veil that separated the Holy of Holies in the Temple (Hebrews 10:20), torn on the Cross for us (the veil in the Temple tore as Christ died, as recorded in Matthew 27:51 and Luke 23:45), so that we can enter the holy place of God's presence, with our "hearts sprinkled clean" of sin through faith in Christ (Hebrews 10:19-22).
As Jesus put it: "You search the Scriptures because you believe they give you eternal life, but the Scriptures point to me! Yet you refuse to come to me so that I can give you this eternal life," (John 5:39, 40).
The Biblical Jesus never claimed to be a manifestation of a Hindu deity nor a mere man who became an enlightened Guru or spiritual teacher. Jesus was 100% God and 100% man. He was the promised Messiah, the unique Son of God, and God the Son, second Person of the Trinity.
The deity of Christ can be seen in several passages:
One of Jesus' names, "Emmanuel," means, "God with us," (Matthew 1:23).
The first verse of John chapter one, speaking of Christ as the Word, says that "the Word was God."
Jesus says in John 8:58 that he is the "I AM" of Exodus 3:14, the name God used for himself in speaking to Moses.
The Jews recognized Jesus' claim of equality with God in John 5:17, 18 as well as in John 10:30-33, when Jesus says that he and the Father are one.
Jesus refers to sharing "God's glory before the world began" in John 17:4.
Philippians 2:6, 7 talks of Christ giving up his glory as God to incarnate.
Thomas, in John 20:28, cries out to Jesus, "My Lord and my God!"
Jesus created and sustains the universe, Hebrews 1:1-3.
Titus 2:13 speaks of "our great God and Savior, Jesus Christ."
Elizabeth, the mother of John the Baptist, says to the newly pregnant Mary in Luke 1:43, "And how has it happened to me, that the mother of my Lord should come to me?" acknowledging Jesus, still in Mary's womb, as "Lord."
Jesus is described as Creator in John 1:3, Colossians 1: 16, 17, and Hebrews 2:10.
Jesus is the Almighty in Revelation 1:8.
Jesus is the Alpha and the Omega in Revelation 1:8, and 22:13 (God is called the Alpha and Omega in Revelation 21:6).
Jesus is worshipped as God by the wise men in Matthew 2:11, by the blind man in John 9:38, by angels in Hebrews 1:6, by the disciples in Matthew 14:33 and Matthew 28:17, by the women at the tomb in Matthew 28:9, and by the 24 elders in Revelation 5:14.
Just as God does not change (Malachi 3:6, James 1:17), neither does Jesus (Hebrews 13:8).
The Hebrew Scriptures testify to the deity of Christ as well:
In Isaiah 9:6, God tells us that one of the names for Jesus is "Mighty God."
Isaiah prophesies of John the Baptist in 40:6, saying that John will call for a highway for "our God," speaking of Jesus; this is fulfilled in John 1:23.
God speaks of every knee bowing to him in Isaiah 45:23; Philippians 2: 10,11 applies this to Jesus.
Jesus, speaking of God the Father in Luke 20:38, says that God is not the God of the dead but of the living, and Romans 14:9 says the very same thing of Christ, "that He might be Lord both of the dead and of the living."
God says in Isaiah 42:8 that he will not give his glory to another, yet Jesus speaks in John 17:5 of the glory he had with God before the world existed.
Joel 2:32 tells us that "whoever calls on the name of the Lord will be delivered," and we see in Romans 10:9, 10, that those who confess Jesus as Lord will be saved.
We humans cannot match the sinlessness of Christ, nor do we fulfill the prophecies of the Messiah in Hebrew Scripture. Those prophecies pointed to one Person, the man Jesus. At Jesus' birth, an angel appearing to the shepherds told them that "today in the city of David there has been born for you a Savior, who is Christ the Lord," (Luke 2:11). Jesus did not become the Christ; he was the Christ at his birth and had always been the Christ, the only Christ.
