Immortality

Some would quote

I urge you in the sight of God Who gives life to all things, and before Christ Jesus who witnessed the good confession before Pontius Pilate, that you keep this commandment without spot, blameless until our Lord Jesus Christ’s appearing, which

• He will manifest in His own time,
• He who is the blessed and
• only Potentate (Sovereign),
• the King of kings and Lord of lords,
• Who alone has immortality,
• dwelling in unapproachable light,
• Whom no man has seen or can see,
• to Whom be honor and everlasting power.

-- 1 Timothy 6:13-16 (NKJV)

Out of context, it seems like Paul say Jesus is God and that Jesus is Sovereign, King of kings, Lord of lords, immortal and almighty, but Paul refers to two persons: "God Who... and before Christ Jesus who...". The question is who is the "He" to "Whom" the attributes apply?

If these attributes apply to Jesus then all of them should apply:

Therefore, this scripture cannot be used to proof that Jesus is God Almighty.

If you believe Jesus cannot die, then you would have a problem with:

Now I would remind you, brothers, of the gospel I preached to you, which you received, hin which you stand, and by which you are being saved, if you hold fast to the word I preached to you — unless you believed in vain.

For I delivered to you as of first importance what I also received:

1. that Christ died for our sins in accordance with the Scriptures,
2. that he was buried,
3. that he was raised on the third day in accordance with the Scriptures, and
4. that he appeared to Cephas, then to the twelve. Then he appeared to more than five hundred brothers at one time, most of whom are still alive, though some have fallen asleep. Then he appeared to James, then to all the apostles. Last of all, as to one untimely born, he appeared also to me.

-- 1 Corinthians 15:1-8

Raising the temple

Some argue that Jesus raised himself from the dead based on:

Jesus answered them, “Destroy this temple, and in three days I will raise it up.” The Jews then said, “It has taken forty-six years to build this temple, and will you raise it up in three days?”

But he was speaking about the temple of his body. When therefore he was raised from the dead, his disciples remembered that he had said this, and they believed the Scripture and the word that Jesus had spoken.

-- John 2:19-22 (ESV)

and

For this reason the Father loves me, because I lay down my life that I may take it up again. No one takes it from me, but I lay it down of my own accord. I have authority to lay it down, and I have authority to take it up again. This charge I have received from my Father. -- John 10:17-18 (ESV)

In both cases Jesus said that he would sacrifice his own life and come to life again. He never claimed to be immortal. In other words: "he can die".

But of God is said:

Are you not from everlasting, O LORD my God, my Holy One? We shall not die. -- Habakkuk 1:12 (ESV)

To the King of the ages, immortal, invisible, the only God, be honor and glory forever and ever. -- 1 Timothy 1:17 (ESV)

God is eternal (Psalm 90:2; Isaiah 40:27; Romans 16:26) and cannot die.

If you confess with your mouth Jesus as Lord, and believe in your heart that God raised him from the dead, you will be saved. -- Romans 10:9

Did Jesus resurrect himself?

No...

This Jesus hath God raised up, whereof we all are witnesses. -- Acts 2:32 (KJV)

God raised him from the dead. -- Acts 13:30 (ESV)

The times of ignorance God overlooked, but now He commands all people everywhere to repent, because He has fixed a day on which He will judge the world in righteousness by a man whom He has appointed; and of this He has given assurance to all by raising him from the dead.” -- Acts 17:30-31 (ESV)

We are even found to be misrepresenting God, because we testified about God that He raised Christ, whom He did not raise if it is true that the dead are not raised. -- 1 Corinthians 15:15 (ESV)
