...He listed the names of the people who would not get thru the cities so how would you get those disciples to still be preaching around the cities of anywhere?...
I don't. Those disciples died before they preached to every city of Israel. Jesus didn't come and instantly transform them while still alive into immortal bodies (1 Corinthians 15:23, 51-53). The 2nd coming hasn't happened yet. The prophecy of Matthew 10:23 will be fulfilled because the 2nd coming will happen before all the cities of Israel have been gone over by his disciples past or present.
...John was to live until His return IF Jesus wanted John to live until His return...
Jesus didn't want that.
"Jesus said not unto him, He shall not die." John died. Jesus wanted Peter to not be jealous of John for not having to be martyred like Peter would be (John 21:19); Jesus wanted Peter to consider his reaction IF Jesus had willed that John never die while Peter would have to die a cruel death.
...I'd stay with the way the interpreters wrote [Col 1: 23] in say KJV...
But note again that the Greek itself doesn't indicate a past tense. And again, if the gospel
had already been preached to everyone, I don't believe Paul would have spoken elsewhere of his desire "to preach the gospel in the regions beyond you, and not to boast in another man's line of things made ready to our hand" (2 Corinthians 10:16), and today's missionaries would not be troubling themselves to reach remote tribes in places like Borneo and the Amazon which have not yet heard the gospel.
...it agrees with Matthew 10 ; 23 as written...
How? Matthew 10:23 says they
wouldn't reach every city of Israel.
...postrib: "When were those who were still alive and in Christ changed in the twinkling of an eye into immortal bodies?"
*************
When they died...
Note that I asked: When were those who were
still alive and in Christ changed in the twinkling of an eye into immortal bodies?
"We shall
not all sleep, but we shall all be changed, In a moment, in the twinkling of an eye, at the last trump" (1 Corinthians 15:51-52).
...the coming of the Kingdom of God is not visible to the living...
Note that in Luke 17:20-21, Jesus was replying to the Pharisees, who expected Christ to conquer the world physically at his 1st coming. He was trying to get them to realize that they had to be conquered on the inside first -- as he had told them previously: all they cared about was externals (Luke 11:39).
Notice that right after Luke 17:20-21, Jesus goes on to explain to his disciples that he had to die first, but that after that he would be revealed to destroy all his enemies (Luke 17:22-30). This is confirmed in other passages, which also foretell the day when the kingdom would come with observation (Revelation 1:7, Matthew 24:30).
...The phrase is "we who are still alive, and remain til the coming......" How do you see this?...
When Paul said "we which are alive and remain unto the coming of the Lord" (1 Thessalonians 4:15), I believe he was referring to we Christians generally, and wasn't including himself, for he knew he was going to die before Jesus came (2 Timothy 4:6), which he did, as did all of the 1st century Thessalonians. 1 Thessalonians 4:15 will be fulfilled because some of us Christians will be alive and remain unto the coming of the Lord, which still has not yet occurred for any of us, for, again, when was Jesus' coming seen by every eye of every tribe and kindred on earth, causing them great grief? (Matthew 24:30 and Revelation 1:7) When were those who were still alive and in Christ changed in the twinkling of an eye into immortal bodies? (1 Corinthians 15:23, 51-53) When was the Antichrist destroyed? (2 Thessalonians 2:8) When did Revelation 19 happen? When were Zechariah 14 and Zechariah 12 fulfilled?
...Note that the Bible doesn't say the resurrection happens at the moment of the death of this or that individual,
******************
Well, when you put together John 11 :25, 26, Hebrews 9 : 27, Luke 23 : 43,1 Cor. 15 :44 and others, what else can it say?...
How do any of these require that the resurrection happens at the moment of the death of this or that individual?
...remaining in graves after dying will continue to be a part of every living mortal creature...
I don't believe so. Note again that at the 1st resurrection (Revelation 20:4-5), the mortal bodies of believers will be resurrected, for Jesus "shall change our vile body, that it may be fashioned like unto his glorious body" (Philippians 3:21), for "if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you" (Romans 8:11), "for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed. For this corruptible must put on incorruption, and this mortal must put on immortality. So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory. O death, where is thy sting? O grave, where is thy victory?" (1 Corinthians 15:52-55)
