The EARTHLY "KINGDOM OF GOD" (Matthew 21:43)
is called the "KINGDOM OF HEAVEN" (Matthew 4:17) - it will be established on the EARTH (Matthew 6:10) when the "GOD OF HEAVEN" (Daniel 2:44)
shall REPLACE the "KINGDOMS OF THIS WORLD" with the KINGDOM "OF HIS CHRIST" (Revelation 11:15)
and then the "LORD OUR RIGHTEOUSNESS" (Jeremiah 23:6) shall REIGN and "shall EXECUTE JUDGMENT and JUSTICE IN THE EARTH"
(Jeremiah 23:5)
In the MILLENIAL REIGN OF CHRIST (Revelation 20:4,6)
- "EVERYONE that is LEFT OF ALL THE NATIONS ... shall even go up from year to year to WORSHIP THE KING, THE
LORD OF HOSTS" (Zechariah 14:16) - IF THEY DON'T then THEIR LAND will have NO RAIN (Zechariah 14:17)
and THEIR BODIES will SUFFER THE PLAGUE (Zechariah 14:18), i.e. "THEIR FLESH shall CONSUME AWAY while they stand upon their
feet" (Zechariah 14:12)
In the MILLENIAL REIGN OF CHRIST - SOME PRIESTS OF THE
LORD shall MARRY (Ezekiel 44:15,22) - THOSE who were NOT MARTYRED by Antichrist (Revelation 12:14-17 cp. Revelation 13:4-7)
and, therefore, THEY will be IN FLESH AND BLOOD BODIES - "for IN THE RESURRECTION they NEITHER MARRY, NOR
are GIVEN IN MARRIAGE" (Matthew 22:30)
Paul speaks of TWO TRUMPS to be SOUNDED at "the GLORIOUS
APPEARING of the GREAT GOD and our SAVIOR JESUS CHRIST" (Titus 2:13)
for "THE CHURCH, which is HIS BODY" (Ephesians 1:22-23) at its "GATHERING TOGETHER unto Him" (II Thessalonians 2:1)
"to MEET the Lord IN THE AIR" (I Thessalonians 4:17)
At the FIRST TRUMP, "the DEAD in Christ shall RISE
FIRST" (I Thessalonians 4:16)
Note that Paul uses the TERMS, LAST and SECOND, INTERCHANGEABLY
elsewhere in the CONTEXT of this SAME CHAPTER - "the LAST Adam" (I Corinthians 15:45) and "the SECOND Man" (I Corinthians 15:47)
