BUSTED - 12 False theories refuted:

Strong in Him said:

1 Timothy 6:12 - take hold of the eternal life which you received .......

Where is Timothy now? If he did actually become immortal then, why did he remain on earth as Pauls helper?
All of your "proofs', can be seen for what they are; the Promise of becoming immortal at the final Judgment.

Our lives are; to God, all about testing and the choices we make.
He has set up our world in a very clever way, so we all can choose our path in life. Basically; those who decide to ignore the plain facts of Creation and live the hedonistic lifestyle, will be discarded at the final Judgment, but those who do acknowledge God, keep His Commandments and believe in Jesus, will be given Eternal life at the GWT Judgment, Revelation 20:11-15, Revelation 21:1-7

Our Hope and our Destiny:
The Prophetic Word tells us how the Lord will save and protect His people during His terrible Day of wrath, the soon to happen Sixth Seal punishment of the ungodly peoples and the reset of our civilization.
Then those who kept strong in their faith will be gathered and will migrate into all of the holy Land. Psalms 107, Ezekiel 34:11-16 and Isaiah 66:18b-21, Isaiah 35:1-10, Romans 9:24-26, are some of the best prophesies about this.

We Christians are the Lord's people, His chosen; John 15:18, 1 Peter 2:8-10, and we are the people; the nation, who bear the proper fruit. Matthew 21:43.
We will, in the holy Land be His witnesses, Isaiah 43:10, John 15:27 and His Light to the nations. Isaiah 49:8, Acts 13:47, Ezekiel 39:27
Basically there is no need for anyone, other than the 2 Witnesses to go to heaven, Revelation 11:12, and they do not stay there, as Jesus Returns just then and they are resurrected along with all the rest of the GT martyrs. Revelation 20:4

The whole idea of a rapture removal of Christians to heaven, is not part of God's plan for His people. We are made to live on earth, God has angels in heaven.
Therefore, a body change is not necessary or logical, before the final wrap up after the Millennium and only then will all those whose names are written in the Book of Life, receive immortality and be with God for Eternity, when God and therefore; heaven will be on the new earth. Revelation 21:1-4
