Certainly, there are saved and unsaved people in every nation; but some nations are so saturated with false religion that nearly all of them are going to Hell. Acts 17:27 teaches us that the reason why God scattered mankind at the Tower of Babel was so they they would “seek the Lord.” Before Babel, the entire world became corrupted, so bad, so fast, that God decided to destroy the world by flood. When Noah and his family got off the ark, they were all Christians. But it was just a matter of time before the world once again went into utter wickedness, and Noah's descendants forsook God.
As hard as it is to imagine, entire nations will be cast into the Lake of Fire. It will be very sad in eternity, when an entire culture is cast into Hell forever. So many people are going to Hell because don't love God more than their own family and nation. This is why Jesus taught that a man must hate his own family (Luke 14:26), in comparison to his love for God. Jesus was teaching that we ought to obey God above all else (Romans 3:4). I know people who won't come out of the Catholic Church because they love their family more than God. It is evil. I know people who won't go soul-winning, because they love this present world (2nd Timothy 4:10). Hardly anyone loves God anymore.
All of the Arab nations today are predominantly Muslim, following the false religion of Islam. Those nations will all be cast into Hell. Only those few individuals who have been born-again in Jesus Christ will be spared the wrath of God in Hell fire. Romans 5:9, “Much more then, being now justified by His blood, we shall be saved from wrath through Him.” Only through faith in the blood of Jesus Christ can anyone be saved from the wrath of God the Father.
The Bible proclaims in Psalm 9:17 that the wicked and ALL THE NATIONS THAT FORGET GOD shall be turned into Hell.
1st John 2:22 plainly teaches that anyone who denies Jesus is the Christ is a LIAR. Anyone who teaches and follows ANOTHER GOSPEL is going to Hell (2nd Corinthians 11:4). The perverted Gospel of the Catholic religion is demonic. As much as I try to warn people and wake them up, most people don't listen. They are fools headed for destruction in Hell.
Sad, but true, entire nations are so wicked and rebellious against the truth that hardly any of them are born-again Christians. I'm not saying that there aren't Christians in every nation; but the number is so few that 99% of it's inhabitants are going to Hell. I'm just preaching the Bible.
