You do err not knowing Scriptue. In Revelation, Chapter 19, which describes the return of Jesus Christ prior to the so-called millennial reign we read:
Revelation 19:11-21, KJV
11. And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war.
12. His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself.
13. And he was clothed with a vesture dipped in blood: and his name is called The Word of God.
14. And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean.
15. And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.
16. And he hath on his vesture and on his thigh a name written, KING OF KINGS, AND LORD OF LORDS.
17. And I saw an angel standing in the sun; and he cried with a loud voice, saying to all the fowls that fly in the midst of heaven, Come and gather yourselves together unto the supper of the great God;
18. That ye may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses, and of them that sit on them, and the flesh of all men, both free and bond, both small and great.
19. And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army.
20. And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.
21. And the remnant were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh.
Now if the above is not a picture of Jesus Christ in the Glory of the Godhead what is it?
In another picture of the return of Jesus Christ we read:
Matthew 24:29, 30 KJV
29. Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
30. And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
A few more for your edification.
Matthew 16:27,28 KJV
27. For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works.
28. Verily I say unto you, There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom.
Matthew 26:64 Jesus saith unto him, Thou hast said: nevertheless I say unto you, Hereafter shall ye see the Son of man sitting on the right hand of power, and coming in the clouds of heaven.
Mark 13:26 And then shall they see the Son of man coming in the clouds with great power and glory.
Mark 14:62 And Jesus said, I am: and ye shall see the Son of man sitting on the right hand of power, and coming in the clouds of heaven.
Luke 21:27 And then shall they see the Son of man coming in a cloud with power and great glory.
So I am still curious, how are people saved in the so-called millennial kingdom?
Of course we musn't forget that wonderful passage from Hebrews:
Hebrews 9:28 So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.
And I am still curious, how are people saved in the so-called millennial kingdom?
