1Ti 6:13 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,
1Ti 6:14 that you keep this commandment without spot, blameless until our Lord Jesus Christ's appearing,
1Ti 6:15 which He will manifest in His own time, He who is the blessed and only Potentate, the King of kings and Lord of lords, 1Ti 6:16 who alone has immortality, dwelling in unapproachable light, whom no man has seen or can see, to whom be honor and everlasting power. Amen.
Nobody has immortality except Christ.
Joh 3:14 And as Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up, Joh 3:15 that whoever believes in Him should not perish but have eternal life.
Joh 3:16 For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.
The choices are "to perish"...and the greek means to be fully destroyed...versus "eternal life". Immortality. Man without Christ does not have any kind of eternal life nor immortality.
1Co 15:51 Behold, I tell you a mystery: We shall not all sleep, but we shall all be changed
1Co 15:52 in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed.
1Co 15:53 For this corruptible must put on incorruption, and this mortal must put on immortality.
A mortal can only put on immortality when Christ returns, at the last trumpet.
There is no "natural" immortality. For Christians the doctrine of the immortal soul WITHOUT Christ should be seen as blasphemous for it proposes immortality WITHOUT Christ.
Rom_6:23 For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.
Eternal life, immortality, is a gift from God. Not accepting that gift means that one is NOT immortal.
I guess that 'everlasting' fire will burn on without inhabitants then.
In Scripture, mortal and immortality refer only to the condition of the body. It is the body that is mortal, never the soul, or spirit.
"This mortal will put on immortality" is speaking of the resurrection of our body, not our spirit. A spirit cannot die. The term resurrection only applies to the body.
Therefore 1 Timothy 6:16, referring to Christ, means the God/man alone has immortality as his nature, and being the firstfruit raised in the resurrection.
Cordially,
