To keep it from being so lengthy I’ll address this one point first.
I disagree with the premise of most of your question, about all I can agree with is “ Jesus said that there is no sex in Heaven”.
You answered part of your own question “FAITHFUL” angels can’t have sex in heaven because Jesus said there is no marriage or sex if you prefer the term, in heaven.
Fallen angels are not demons, another topic.
There are no demons in heaven.
There are no humans in heaven, only the departed spirits of dead believers. 2 Corinthians 5:8,
Fallen angels rebelled and followed satan and only some of them took the extra step to co habit with human women.
Jude 6 And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.
1. All fallen angels are not in chains.
2. The ones that are in chains made some choice that the rest of the fallen angels did not make . I can’t recall where you have actually addressed this point. Correct me if I’m wrong. 2 Peter 2:4, Jude 6
I understand how you interpret Matthew 22:30. Just as you accuse me of denying the words of Jesus I accuse you of not dealing with the actual wording of the text and insert your own opinion.
1. We are not talking about angels that are in heaven.
2. We are not talking about anything that happened in heaven or will ever happen
3. We are talking about fallen angels who don’t think twice about violating God’s order.
4. You can’t show me one word in the text Of Matthew 22:30 that applies to a fallen angel on the earth.
5. You can’t prove what the anatomy is of any of God’s creatures based on the statement there is no marriage in heaven.
Matthew 22:30 For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven.
We may disagree on what we think this verse means , but I do not believe we can disagree on what it says .
It does not say that “angels are ASEXUAL and can not have sex.”
You said..............
"Fallen angels are not demons, another topic."
I disagree with that idea. There is IMO no doubt these fallen angels are now known as the demons.
We know that hell was prepared for the devil and his angels, according to
Matthew 25:41:........... “Then He will say to those on His left, ‘Depart from me, you who are cursed, into the eternal fire prepared for the
devil and his angels.’”
Hermeneutically speaking, Jesus, by using the possessive word his makes it clear that these angels belong to Satan.
Revelation 12:7-9 describes an end-times angelic battle between Michael and "his angels" and the devil and "his angels." From these and similar verses, it is clear that demons and fallen angels are synonymous.
You reject the Biblical explination that the demons are the fallen angels due to the fact that Jude verse 6 declares the angels who sinned to be "bound with everlasting chains." However, it is clear that not all of the angels who sinned are "bound," as Satan is still free as recorded in
1 Peter 5:8.
Why would God imprison the rest of the fallen angels, but allow the leader of the rebellion to remain free? It seems that Jude verse 6 is referring to God confining the fallen angels who rebelled in an additional way.
While the Bible does not specifically say what happened to the souls of the Nephilim when they were killed, it is unlikely that God would destroy the Nephilim in the Flood only to allow their souls to cause even greater evil as the demons. The most biblically consistent explanation for the origin of the demons is that they are the fallen angels, the angels who rebelled against God with Satan.
Now honestly, the only reason you argue the point of asexual angels told to us in Matt. 22:30 is because it destroys your theology of demons having sex with humans.
I really hate to say this, but I just do not understand how you can dismiss the Scriptures so easily in order to believe what you want to believe.
1st Corinthians 15:39,40 is very, very clear...........
"All flesh is not the same flesh: but there is one kind of flesh of men, another flesh of beasts, another of fishes, and another of birds.
There are also celestial bodies, and bodies terrestrial: but the glory of the celestial is one, and the glory of the terrestrial is another."
Then Genesis 1:24...........
And God said, “Let the earth bring forth living creatures according to their kinds—livestock and creeping things and beasts of the earth according to their kinds.” And it was so.
How can you read those Scriptures and still believe that demons/fallen angels had sex with humans????
