“At that time Michael shall stand up, =
Revelation
The great prince who stands
watch over the sons of your people;
And there shall be a time of trouble, = Matt chapter 24 = as in the days of Noah so shall the Coming of the Son of Man be
Such as never was since there was a nation,
Even to that time.
And at that time your people shall be delivered, = 1 Thess 1:10
Every one who is found written in the book. = Luke 10:20
2And many of those who sleep in the dust of the earth shall awake,
Some to everlasting life, = Matt 22:29-32 = 1 Corinthians ch15 , 1 Thessalonians 4:13-18
Some to shame
and everlasting contempt.
3Those who are wise shall shine
Like the brightness of the firmament,
And those who turn many to righteousness
Like the stars forever and ever.
John 6:35-40
And Jesus said to them, “I am the bread of life. He who comes to Me shall never hunger, and he who believes in Me shall never thirst.
36But I said to you that you have seen Me and yet do not believe.
37All that the Father gives Me will come to Me, and the one who comes to Me I will by no means cast out.
38For I have come down from heaven, not to do My own will, but the will of Him who sent Me.
39This is the will of the Father who sent Me, that of all He has given Me I should lose nothing,
but should raise it up at the last day.
40And this is the will of Him who sent Me, that everyone who sees the Son and believes in Him may have everlasting life; and
I will raise him up at the last day.”
1 Corinthians 15:20-23
But now Christ is risen from the dead,
and has become the firstfruits of those who have fallen asleep.
21For since by man
came death, by Man also
came the resurrection of the dead.
22For as in Adam all die, even so in Christ all shall be made alive.
23But each one in his own order: Christ the firstfruits, afterward those
who are Christ’s at His coming.
Revelation 6:9-11
When He opened the fifth seal, I saw under the altar the souls of those who had been slain for the word of God and for the testimony which they held.
10And they cried with a loud voice, saying, “How long, O Lord, holy and true, until You judge and avenge our blood on those who dwell on the earth?”
11Then a white robe was given to each of them; and it was said to them that they should rest a little while longer, until both
the number of their fellow servants and their brethren, who would be killed as they
were, was completed.
GOD never lies
