Gen 6:4-5 There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown. And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
Did the sons of God and daughters of men create giants? The word Giants is used thirteen times in the Old Testament, and is simply in reference to a larger or taller people.
Num 13:33 And there we saw the giants, the sons of Anak, which come of the giants: and we were in our own sight as grasshoppers, and so we were in their sight.
Where there Giants on the earth? Yes they were very tall people, but they were just people.
Deut 9:1-2Hear, O Israel: Thou art to pass over Jordan this day, to go in to possess nations greater and mightier than thyself, cities great and fenced up to heaven, A people great and tall, the children of the Anakims, whom thou knowest, and of whom thou hast heard say, Who can stand before the children of Anak!
The reference to the Sons of God is simply a description given unto those who walked with God. To proclaim that the fallen Angels are the sons of God is not supported by logic or Scripture.
Romans 8:13-14 For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live. For as many as are led by the Spirit of God, they are the sons of God.
Matt 5:9 Blessed are the peacemakers: for they shall be called the children of God.
Romans 8:15-16 For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father. The Spirit itself beareth witness with our spirit, that we are the children of God:
Gal 3:26 For ye are all the children of God by faith in Christ Jesus.
Gal 4:5-7To redeem them that were under the law, that we might receive the adoption of sons. And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father. Wherefore thou art no more a servant, but a son; and if a son, then an heir of God through Christ.
Mark 12:25 For when they shall rise from the dead, they neither marry, nor are given in marriage; but are as the angels which are in heaven.
Unless you consider Jesus Christ a liar, fallen Angels can never have sexual relations with humans.
Heb 1:4-5 Being made so much better than the angels, as he hath by inheritance obtained a more excellent name than they. For unto which of the angels said he at any time, Thou art my Son, this day have I begotten thee? And again, I will be to him a Father, and he shall be to me a Son?
None of the Angels were ever considered the sons of God.
Heb 1:7 And of the angels he saith, Who maketh his angels spirits, and his ministers a flame of fire.
Heb 1:13-14But to which of the angels said he at any time, Sit on my right hand, until I make thine enemies thy footstool? Are they not all ministering spirits, sent forth to minister for them who shall be heirs of salvation?
Angels are spiritual beings, and only God’s Angels are given the power to minister to his Elect.
Heb 2:16 For verily he took not on him the nature of angels; but he took on him the seed of Abraham.
God was manifest in the flesh.
There is an incredible difference between the nature of man and Angels.
Eph 6:12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
Luke 24:39-40 Behold my hands and my feet, that it is I myself: handle me, and see; for a spirit hath not flesh and bones, as ye see me have. And when he had thus spoken, he shewed them his hands and his feet.
Angels are spiritual beings and do not have true physicality, except for when God allows it. Angels are God’s ministers to his people. The interaction in the physical or flesh, between the fallen Angels and humans, is not mentioned anywhere in Scripture.
Psalms 104:4-5 Who maketh his angels spirits; his ministers a flaming fire: Who laid the foundations of the earth, that it should not be removed for ever.
Heb 1:7-8 And of the angels he saith, Who maketh his angels spirits, and his ministers a flame of fire. But unto the Son he saith, Thy throne, O God, is for ever and ever: a sceptre of righteousness is the sceptre of thy kingdom.
Heb 1:13-14 But to which of the angels said he at any time, Sit on my right hand, until I make thine enemies thy footstool? Are they not all ministering spirits, sent forth to minister for them who shall be heirs of salvation?
To imagine then that the fallen angels could become human, that is to be creators, and have sexual relations with God’s creation is simply absurd.
2 Peter 2:4 For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment;
There is nothing to suggest the fallen angels have any true power at all. The spirit of Satan may if invited enter into the heart of a man, but that is the extent of his power (Mark 4:15, Luke 22:3, 1 Tim 5:15, Rev 2:9).
Jude 1:5-6 I will therefore put you in remembrance, though ye once knew this, how that the Lord, having saved the people out of the land of Egypt, afterward destroyed them that believed not. 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.
Rev 12:7-9 And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels, And prevailed not; neither was their place found any more in heaven. And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
The reference to angels is used 186 times in the New Testament, and only five verses are in reference to Satan and or his angels (2 Cor 11:4; 2 Cor 12:7; Rev 9:11; Rev 12:9).
There is not one verse in the entire Bible referring to any fallen Angel other than Satan, having any interrelation with God’s creation in a physical nature.
Gen 6:6-7 And it repented the LORD that he had made man on the earth, and it grieved him at his heart. And the LORD said, I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air; for it repenteth me that I have made them.
God destroyed mankind that He created, because of their wickedness. If there was a group of supernatural fallen Angels that created giants, He would have mentioned them as well?
2 Tim 3:5-7Having a form of godliness, but denying the power thereof: from such turn away. For of this sort are they which creep into houses, and lead captive silly women laden with sins, led away with divers lusts, Ever learning, and never able to come to the knowledge of the truth.
The sons of God and daughters of men false doctrine, is just one of many fables!
