Now, here's a tough question for annihilationists. Was Jesus talking about the 24-hour day he died on when he told the good thief, "Today you will be with me in paradise?" If he was talking about it, did the good thief die and come back to life to visit paradise? Did the Savior do that? St. Thomas would call a disembodied human soul by its person's name. So maybe Our Lord meant that his soul would visit paradise with the thief's soul.
I can't speak for others, personally I don't see that as a tough question when we factor in other things, such as what the thief said. Though, I'm not certain what your point is in regards to annihilation and how it relates to this?
Luke 23:42 And he said unto Jesus, Lord, remember me when thou comest into thy kingdom.
43 And Jesus said unto him, Verily I say unto thee, To day shalt thou be with me in paradise.
Take note what the thief said in verse 42---remember me when thou comest into thy kingdom
The question then is, since verse 43 in regards to paradise obviously has to be involving Him coming into His kingdom, did Jesus come into His kingdom the very day He died? No. Unless one thinks the following is pertaining to coming into His kingdom.
Matthew 12:40 For as Jonas was three days and three nights in the whale's belly; so shall the Son of man be three days and three nights in the heart of the earth.
I propose that when He comes into His kingdom it is meaning once He bodily returns in the future, which then involves raising the dead, which then involves the new Jerusalem coming down from God out of heaven. And speaking of that, by putting 2 and 2 together per the following, we can then assume the paradise Jesus was referring to in Luke 23:42 is likely meaning the new Jerusalem.
Revelation 2:7 He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the tree of life, which is in the midst of the paradise of God.
This verse tells us that the tree of life, it is in the midst of the paradise of God. Where does the book of Revelation then tell us where the tree of life is? Does it not tell us it is in the new Jerusalem?
Revelation 21:2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.
Revelation 22:2 In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations.
