Again, thank you for your valuable input with scripture.
a.) If no unbeliever survives then no one is left for the KING of kings to rule over.
He has ruled over His kingdom for the past almost 2,000 years already and He will deliver the kingdom to the Father when He returns (1 Cor 15:22-24) and rule over all believers from all-time with the Father for eternity at that point. Is that not enough?
b.) God said HE will not destroy everyone at His Second Coming = Zechariah chapter 14
And it shall come to pass that everyone who is left of all the nations which came against Jerusalem shall go up from year to year to worship the King, the Lord of hosts, and to keep the Feast of Tabernacles.
How does your understanding of Zechariah 14 line up with passages like these from the more enlightened New Testament?
Matthew 24:
35
Heaven and earth will pass away, but my words will never pass away. 36 “
But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father. 37 As it was in the days of Noah, so it will be at the coming of the Son of Man. 38 For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark; 39 and
they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man.
In this passage Jesus talks about His second coming in relation to heaven and earth passing away and He made the point that just as all unbelievers were killed in the flood in Noah's day "That is how it will be at the coming of the Son of Man". So, He was saying that just as all unbelievers were killed in the flood, that is what will happen when He returns as well. And you know Jesus would never contradict other scripture, so you should consider that you may be misinterpreting Zechariah 14 since your interpretation does not line up with what Jesus Himself taught about what will happen when He returns.
2 Thessalonians 1:6 God is just: He will pay back trouble to those who trouble you 7 and give relief to you who are troubled, and to us as well.
This will happen when the Lord Jesus is revealed from heaven in blazing fire with his powerful angels. 8 He will punish those who do not know God and do not obey the gospel of our Lord Jesus. 9 They will be punished with everlasting destruction and shut out from the presence of the Lord and from the glory of his might 10 on the day he comes to be glorified in his holy people and to be marveled at among all those who have believed. This includes you, because you believed our testimony to you.
In this passage Paul indicates that Jesus will be punishing "those who do not know God and do not obey the gospel of our Lord Jesus" when He comes again. So, where did he make any exceptions that would allow any unbelievers to not experience His wrath at that time? He didn't. So, why interpret Zechariah 14 in such a way that contradicts what Paul taught? That is not a good idea.
And then there are these passages which speak of the wrath that will occur on the day Jesus returns:
1 Thess 5:1 Now, brothers and sisters, about times and dates we do not need to write to you, 2 for you know very well that
the day of the Lord will come like a thief in the night. 3 While people are saying, “Peace and safety,” destruction will come on them suddenly, as labor pains on a pregnant woman, and they will not escape.
2 Peter 3:10 But
the day of the Lord will come like a thief. The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything done in it will be laid bare. 11 Since
everything will be destroyed in this way, what kind of people ought you to be? You ought to live holy and godly lives 12 as you look forward to the day of God and speed its coming. That day will bring about the destruction of the heavens by fire, and the elements will melt in the heat. 13
But in keeping with his promise we are looking forward to a new heaven and a new earth, where righteousness dwells.
What Paul and Peter taught will happen on the day Christ returns is that the Lord's wrath will come down suddenly and unexpectedly like a thief in the night and it will be by way of fire and the destruction will be so complete that Paul said "they will not escape". Fire will come down upon the entire earth and there will be nowhere for unbelievers to escape (believers will have been caught up to meet the Lord "in the air" at that point).
So, why does your interpretation of Zechariah 14 not line up with what Paul and Peter taught? I'm certain that they had a much better understanding of Zechariah 14 than either you or I do and they clearly did not have the same understanding of Zechariah 14 as you do. That is something you need to take into consideration. Currently, you are interpreting one passage in such a way that contradicts other passages of scripture. That is not acceptable. The New Testament sheds light on the more obscure Old Testament. Please allow the New Testament to interpret the Old Testament prophecies for you. It's much easier that way.
