The Offspring of God

I believe Scripture presents humanity as the offspring of God, created from one human family (Acts 17:26–29). 

Although all humanity is presently subject to death in Adam, God’s purpose in Christ is that all shall ultimately be made alive, each in his own order (1 Corinthians 15:22–23). 

Christ died not for Israel only, but to gather the scattered children of God into one (John 11:51–52). 

In the fullness of times, God will gather together in one all things in Christ, both those in heaven and those on earth (Ephesians 1:9–10). 

Christ is the Head, and the ecclesia is His body (Ephesians 1:22–23). 

Therefore, I believe that God’s ultimate purpose is for everyone to become a member of the body of Christ, each in his own order, until all things are subjected to Christ and ultimately “God may be all in all” (1 Corinthians 15:24–28).

Death is to be "Swallowed Up in Victory"!

 "He will Swallow up death in Victory; and the Lord GOD will wipe away tears from off all faces; and the rebuke of His people shall He take away from off all the earth: for the LORD hath spoken it. And it shall be said in that day, Lo, this is our God; we have waited for Him, and He will save us: this is the LORD; we have waited for Him, we will be glad and rejoice in His salvation." (Isaiah 25:8-9)

Does death being swallowed up in victory only apply to Israel?

No, it applies to all nations. Paul, the apostle to all nations, quotes Isaiah in his letter to Corinth...

"For even as, in Adam, ALL are dying, thus also, in Christ, shall ALL be vivified...Lo! a secret to you am I telling! We all, indeed, shall not be put to repose, yet WE ALL shall be changed, in an instant, in the twinkle of an eye, at the last trump. For He will be trumpeting, and the dead will be roused incorruptible, and we shall be changed. For this corruptible must put on incorruption, and this mortal put on immortality. Now, whenever this corruptible should be putting on incorruption and this mortal should be putting on immortality, then shall come to pass the word which is written, Swallowed up was Death by Victory." (1 Corinthians 15:22, 51-54)

"And the One seated on the throne said, “Behold, I make all things new.” Then He said, “Write this down, for these words are faithful and true.” (Revelation 21:5)

I heard about a mansion
He has built for me in glory.
And I heard about the streets of gold
Beyond the crystal sea;
About the angels singing,
And the old redemption story,
And some sweet day I'll sing up there
The song of Victory!
