"Is the deity of Christ a biblical truth?"

Define Deity: 1. a god or goddess.
2. divine character or nature, especially that of the Supreme Being; divinity.
3. the estate or rank of a god:
4. a person or thing revered as a god or goddess:
    a society in which money is the only deity.
5. the Deity, God; Supreme Being.

In addition to Jesus' specific claims about Himself, His disciples also acknowledged the deity of Christ. They claimed that Jesus had the right to forgive sins—something only God can do—as it is God who is offended by sin (Acts 5:31, "Him God has exalted to His right hand to be Prince and Savior, to give repentance to Israel and forgiveness of sins. (NKJV);
Colossians 3:13, “bearing with one another, and forgiving one another, if anyone has a complaint against another; even as Christ forgave you, so you also must do.” (NKJV)
Psalm 130:4, “But there is forgiveness with You, That You may be feared.” Jeremiah 31:34, "No more shall every man teach his neighbor, and every man his brother, saying, 'Know the LORD,' for they all shall know Me, from the least of them to the greatest of them, says the LORD. For I will forgive their iniquity, and their sin I will remember no more."

In close connection with this last claim, Jesus is also said to be the one who will judge the living and the dead. 2 Timothy 4:1 Paul says, “I charge you therefore before God and the Lord Jesus Christ, who will judge the living and the dead at His appearing and His kingdom:”
John 20:28 Thomas cried out to Jesus, “My Lord and my God!”
Paul mentions Jesus in Titus 2:13 and says, “looking for the blessed hope and glorious appearing of our great God and Savior Jesus Christ,” and he points out that before His incarnation Jesus existed in the “form of God” Phil. 2:5-8

Even God speaks of Jesus in Heb. 1:8: “Your throne, O God, will last forever and ever.” John 1:1 says “in the beginning was the Word, and the Word was with God, and the Word [Jesus] was God.”
Some examples of Scriptures that teach the deity of Christ are many.

Rev. 1:17, “And when I saw Him, I fell at His feet as dead. But He laid His right hand on me, saying to me, "Do not be afraid; I am the First and the Last.”
Rev. 2:8, “And to the angel of the church in Smyrna write, 'These things says the First and the Last, who was dead, and came to life:”
Rev. 22:13, “I am the Alpha and the Omega, the Beginning and the End, the First and the Last.”

1 Corinthians 10:4, “and all drank the same spiritual drink. For they drank of that spiritual Rock that followed them, and that Rock was Christ.”

1 Peter 2:6-8, “Therefore it is also contained in the Scripture, "Behold, I lay in Zion A chief cornerstone, elect, precious, And he who believes on Him will by no means be put to shame." 7 Therefore, to you who believe, He is precious; but to those who are disobedient, "The stone which the builders rejected Has become the chief cornerstone," 8 and "A stone of stumbling And a rock of offense." They stumble, being disobedient to the word, to which they also were appointed.”

Psalm 18:2, “The LORD is my rock and my fortress and my deliverer; My God, my strength, in whom I will trust; My shield and the horn of my salvation, my stronghold.”
Psalm 95:1, “Oh come, let us sing to the LORD! Let us shout joyfully to the Rock of our salvation.”

1 Peter 5:4, “and when the Chief Shepherd appears, you will receive the crown of glory that does not fade away.”

Hebrews 13:20, “Now may the God of peace who brought up our Lord Jesus from the dead, that great Shepherd of the sheep, through the blood of the everlasting covenant,”

Even one of these is enough to show that Christ was considered to be God by His followers.
Jesus is also given titles that are unique to YHWH (the formal name of God) in the Old Testament. The Old Testament title “redeemer” (Psalm 130:7; Hosea 13:14) is used of Jesus in the New Testament.

In Titus 2:13, “looking for the blessed hope and glorious appearing of our great God and Savior Jesus Christ,”

Revelation 5:9, “And they sang a new song, saying: "You are worthy to take the scroll, And to open its seals; For You were slain, And have redeemed us to God by Your blood Out of every tribe and tongue and people and nation,”

Jesus is called Emmanuel—“God with us”—in Matthew 1.

In Zechariah 12:10, it is YHWH who says, “They will look on me, the one they have pierced.”

But the New Testament applies this to Jesus' crucifixion in John 19:37, “And again another Scripture says, "They shall look on Him whom they pierced.”

Revelation 1:7, “Behold, He is coming with clouds, and every eye will see Him, even they who pierced Him.”

If it is YHWH who is pierced and looked upon, and Jesus was the one pierced and looked upon, then Jesus is YHWH.

Paul quotes Isaiah 45:22-23 as applying to Jesus in Philippians 2:10-11 when he says, “that at the name of Jesus every knee should bow, of those in heaven, and of those on earth, and of those under the earth, 11 and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.”

Even more, Jesus' name is used alongside God's in prayer “Grace and peace to you from God our Father and the Lord Jesus Christ” (Galatians 1:3; Ephesians 1:2).
This would be blasphemy if Christ were not deity. The name of Jesus appears with God's in Jesus' commanded to baptize “in the name [singular] of the Father and of the Son and of the Holy Spirit” (Matthew 28:19; 2 Cor. 13:14).
Certain actions that can be accomplished only by God are credited to Jesus. Jesus not only raised the dead (John 5:21, 11:38-44) and forgave sins (Acts 5:31, 13:38), He created and sustains the universe (John 1:2; Colossians 1:16-17).

This becomes even clearer when we consider YHWH said He was alone during creation. Isaiah 44:24, “Thus says the LORD, your Redeemer, And He who formed you from the womb: "I am the LORD, who makes all things, Who stretches out the heavens all alone, Who spreads abroad the earth by Myself;”

Christ possesses attributes that only deity can have: He is eternal (John 8:58, “Jesus said to them, "Most assuredly, I say to you, before Abraham was, I AM.” He is omnipresent (Matthew 18:20, “"For where two or three are gathered together in My name, I am there in the midst of them.” Matt. 28:20, “"teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age." Amen.”

He is also omniscient. Matthew 16:21, “From that time Jesus began to show to His disciples that He must go to Jerusalem, and suffer many things from the elders and chief priests and scribes, and be killed, and be raised the third day.”

He is omnipotent. John 11:38-44, “43 Now when He had said these things, He cried with a loud voice, "Lazarus, come forth!” Lazarus was raised from the dead by the power of Christ.

It's one thing to claim to be God or to fool someone into believing it is true, and something else entirely to prove it to be so. Christ offered many miracles as proof of His claim to deity. Just a few of Jesus' miracles include turning water to grape juice (John 2:7), walking on water (Matthew 14:25), multiplying physical objects (John 6:11), healing the blind (John 9:7), the lame (Mark 2:3), and the sick (Matthew 9:35; Mark 1:40-42), and even raising people from the dead (John 11:43-44; Luke 7:11-15; Mark 5:35).


Even more, Christ Himself rose from the dead. Far from the so-called dying and rising gods of pagan mythology, nothing like the resurrection is seriously claimed by other religions, and no other claim has as much confirmation outside the Bible.

There are at least twelve historical facts about Jesus that even non-Christian critical scholars have admitted:

1. Jesus died by crucifixion.
2. He was buried.
3. His death caused the disciples to despair and lose hope.
4. Jesus' tomb was discovered (or was claimed to be discovered) to be empty a few days later.
5. The disciples claimed to experienced appearances of the risen Jesus.
6. After that, they were transformed from doubters into bold believers.
7. This message was the center of preaching in the early Church.
8. This message was preached in Jerusalem.
9. As a result of this preaching, the Church was born and it grew.
10. Resurrection day, Sunday, replaced the Sabbath (Saturday) as the primary day of worship.
11. James, a skeptic, was converted when he also believed that he saw the resurrected Jesus.
12. Paul, an enemy of Christianity, was converted by an experience which he believed to be an appearance of the risen Jesus.

Even if someone were to object to this specific list, only a few are needed to prove the resurrection and establish the gospel: Jesus' death, burial, resurrection, and appearances (1 Cor. 15:1-6). While there may be some theories to explain one or two of the above facts, only the resurrection explains and accounts for them all.

Critics admit that the disciples claimed they saw the risen Jesus. Neither lies nor hallucinations can transform people the way the resurrection did. First, what would they have had to gain? Christianity was not popular and it certainly did not make them any money or fame. Second, liars do not make good martyrs.
There is no better explanation for the resurrection than the disciples' willingness to die horrible deaths for their faith.

It is true that many people have died for lies that they thought were true, but people don't die for what they know is untrue.

In conclusion, Christ claimed He was YHWH, that He was deity (not just “a god” but the one true God); His followers (Jews who would have been terrified of idolatry) believed Him and referred to Him as God. Christ proved His claims to deity through miracles, including the world-altering resurrection. No other reasoning can explain these facts. The bottom line, yes, the deity of Christ is biblical.
