We are looking at generalities! Before the cross the Gentiles were considered blind, ignorant, in bondage and living in darkness, deceived by the father of lies. Satan had them hoodwinked. He ruled the nations. He had them under his control. After the resurrection, the Gentiles were no longer deceived as the Gospel light shone throughout the nations. The veil of ignorance was lifted. They are now without excuse.
You seem to miss what Revelation 20 is talking about and overlook the seismic change in regard to the Gospel opportunity that exists today (in comparison to before the cross) in regard to the nations access to truth.
This truth is highlighted in Matthew 4:8-9 where
“the devil taketh him up into an exceeding high mountain, and sheweth him all the kingdoms of the world, and the glory of them; And saith unto him, All these things will I give thee, if thou wilt fall down and worship me.”
During the temptations of Christ in the desert, Satan offers Jesus the world if He would only bow down before him. Satan was well within his rights to make such an offer since Adam handed over world dominion to him when he allowed himself to be subject to Satan's will.
The parallel passage in Luke 4:5-7 says:
“And the devil, taking him up into an high mountain, shewed unto him all the kingdoms of the world in a moment of time. And the devil said unto him, All this power will I give thee, and the glory of them: for that is delivered unto me; and to whomsoever I will I give it. If thou therefore wilt worship me, all shall be thine.”
Manifestly, through Adam’s sin, Satan was able to present a legitimate temptation to Christ. The fact the devil had the capability to tempt the Lord with this enticement proves he enjoyed authority over the nations that had to be broken. Ultimately, God permitted Satan to have this authority. But it was Adam that relinquished this rule over the earth in the Fall. After all, this was a definite and a real legitimate temptation. The devil had huge power over this world.
God controlled one single nation. Satan controlled the nations plural.
Acts 14:16 confirms that God
“in times past suffered all nations (
ethnos)
to walk in their own ways.”
Acts 17:30 says,
“And the times of this ignorance God winked at; but now commandeth all men every where to repent.”
Ephesians 2:11-13 confirms this, saying,
“ye being in time past Gentiles (
ethnos)
in the flesh, who are called uncircumcision by that which is called the Circumcision in the flesh made by hands; That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world: but now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ.”
Did that mean that all Gentiles were wholesale lost or deceived? No! Many Gentiles found Christ in the OT. It was a general observation at the prevailing spiritual condition of the mass of the people. That is all Rev 20 is saying.
The Scriptures often depict the Gentiles in the Old Testament as deceived, without hope, blinded, ignorant and darkened. The Bible repeatedly describes the Gentiles in the New Testament as enlightened. That does not suggest that all were blind in the Old Testament or that all will be enlightened in the New Testament. These are simply sweeping generalities establishing the Gospel climate in either era. The widespread light didn’t shine on the nations throughout the Old Testament. Today, it does exist as the Gospel is preached throughout the nations. Before the cross, the Gospel was largely withheld from the nations. After the cross, the Gospel spread like wildfire throughout the globe. Like Israel in the Old Testament, the Gentiles in the New Testament have now had the light shone on them through the great commission.
Imprisonment, blindness, darkness, hopelessness and ignorance are always tied together in Scripture.
Isaiah 60:1-3 says,
“Arise, shine; for thy light is come, and the glory of the LORD is risen upon thee. For, behold, the darkness shall cover the earth, and gross darkness the people: but the LORD shall arise upon thee, and his glory shall be seen upon thee. And the Gentiles shall come to thy light, and kings to the brightness of thy rising.”
Isaiah 61:1 says,
“The Spirit of the Lord GOD is upon me; because the LORD hath anointed me to preach good tidings unto the meek; he hath sent me to bind up the broken hearted, to proclaim liberty to the captives, and the opening of the prison to them that are bound.”
Zacharias the father of John the Baptist was filled with the Holy Ghost in Luke 1:78-80 and prophesied:
“Through the tender mercy of our God; whereby the dayspring from on high hath visited us, To give light to them that sit in darkness and in the shadow of death, to guide our feet into the way of peace.”
Simeon acknowledged in Luke 2:30-32 says:
“For mine eyes have seen thy salvation, Which thou hast prepared before the face of all people; A light to lighten the Gentiles, and the glory of thy people Israel."
Prior to Christ’s earthly ministry believers knew that the Gospel was going to go the Gentiles.
The general broad deception that engulfed the Gentiles in ignorance and darkness is lifted. They now can receive if they believe. That does not suggest the majority will. Acts 13:46-48 says,
“Paul and Barnabas waxed bold, and said, it was necessary that the word of God should first have been spoken to you [the Jews]: but seeing ye put it from you, and judge yourselves unworthy of everlasting life, lo, we turn to the ethnos (or)
Gentiles. For so hath the Lord commanded us, saying, I have set thee to be a light of the ethnos (or)
Gentiles, that thou shouldest be for salvation unto the ends of the earth. And when the ethnos (or)
Gentiles heard this, they were glad, and glorified the word of the lord: and as many as were ordained to eternal life believed.”
From Acts 10 (and the incident at Cornelius’ house) the Gospel was released unto the darkened Gentiles in a significant manner. They would now be brought from darkness of heathenism unto the light of Christ and His Gospel. The unequivocal words from Paul and Barnabas above confirm that the tide had markedly turned and that the Gospel had opened up to the blinded Gentiles in a very definite way. With the rare exception of the city of Nineveh, the Gospel was previously restricted to the small individual “nation” of natural Israel before the Cross. The nations were totally engulfed with a blanket of darkness which was now being removed. The enforcement of Satan’s defeat at the Cross would now be realized by the people of God through the faithful preaching of the Word of God. The devil would be spiritually bound as the kingdom of God advanced with the Gospel. This spiritual binding ensures he is unable to defeat the work of the Church of Jesus Christ evangelizing the nations. It was only after Calvary that the good news of salvation was widened out to embrace the heathen “nations” of the world.
For example, Romans 9:30 attests:
“the Gentiles, which followed not after righteousness, have attained to righteousness, even the righteousness which is of faith.”
Many times the New Testament uses broad sweeping statements about the salvation of the Gentiles. This in Rev 20 is just another parallel teaching. It is written throughout the New Testament. Satan has lost his wholesale deception of the Gentile nations. Revelation 20 is one of many general sweeping unqualified statements pertaining to the lifting of the deception on the Gentile nations. This started 2000 years ago. The first resurrection enabled the enlightenment of the nations.
