Genesis 6
The Wickedness and Judgment of Man
1 Now it came to pass, when MEN began to multiply on the face of the earth, and daughters were born to them, 2 that the SONS of God saw the daughters of MEN, that they were beautiful; and they took wives for themselves of all whom they chose.3 And the LORD said, “My Spirit shall not strive[a] with MAN forever, for he is indeed flesh; yet his days shall be one hundred and twenty years.” 4 There were Giants on the earth in those days, and also afterward, when the sons of God came in to the daughters of men and they bore children to them. Those were the mighty men who were of old, men of renown.
There are some who believe the sons of God mentioned in this passage are angels/nephelim.
Let's use the same passage to prove this belief wrong.
(SONS)
bên
bane
From H1129; a son (as a builder of the family name), in the widest sense (of literal and figurative relationship, including grandson, subject, nation, quality or condition, etc.
of
(God)
'ĕlôhı̂ym
el-o-heem'
Plural of H433; gods in the ordinary sense; but specifically used (in the plural thus, especially with the article) of the supreme God; occasionally applied by way of deference to magistrates; and sometimes as a superlative: - angels, X exceeding, God (gods) (-dess, -ly), X (very) great, judges, X mighty.
(Giants)
nef-eel', nef-eel'
From H5307; properly, a feller, that is, a bully or tyrant: - giant.
-From the context of the meaning of the words sons and God we can clearly see that the crowd that is being pointed to by definition of the words used cannot be pointed back to angelic beings.
-Also notice when the sons of God bore children to the daughters of men they gave birth to MEN of RENOWN, this word literally means honor,fame, or authority. Nowhere does it say they were hybrid human beings or despicable creatures.
*Now some will try to argue this with the passage of Jude below.
Jude
6 And the angels who did not keep their proper domain, but left their own abode, He has reserved in everlasting chains under darkness for the judgment of the great day;
-What is the domain of angels? Heaven, where they are supposed to serve God. These angels were kicked out because they followed lucifer.
7 as Sodom and Gomorrah, and the cities around them in a similar manner to these(speaking of sodom and gomorrah), having given themselves over to sexual immorality and gone after strange flesh, are set forth as an example, suffering the vengeance of eternal fire.
-What is the context of verse 6 to which verse 7 is the compliment? Things (in this case angels) went away from were they belonged. What did sodom and gomorrah do that was out of place? Give themselves over to sexual immorality. What will both the people in sodom and gomorrah and the angels who went out of place receive? vengeance of eternal fire.
*And finally the logical argument.
-What are angels? They are creatures that exist outside of our dimension, that ONLY with the permission and purpose of God can reveal themselves in this dimension.
-What are fallen angels? Angels that decided to follow satan.
-Who is satan? he was the most beautiful angel God created who decided he wanted to receive glory instead of giving glory to God.
ALL entities, regardless if they serve God or not, tremble at the name of Jesus. Satan cannot do anything unless God has allowed Him to. However, to those who have not received Christ they are property of satan and he could do anything he pleases to them because just as he told Jesus Christ, these worldly kingdoms were given to him to give to anyone he pleases.
However, logically these creatures have no need to reproduce since their war playground lays in the spiritual realm, which is fought against in the mind, whose fruits are shown in the behavior of people. Their one desire is to be worshiped, and so exhibiting the behaviors they promote is complying with this desire.
God Bless you all!
