Did God have any power over the 9/11 terrorist attack on America?
Yes, because the Bible says God intervenes in the lives of nations and men.
God intervenes in the lives of both nations and individuals because He cares for them and has a purpose for them. Regarding nations, he promises to bless those who follow Him and curse those who do not (see Deut. chapters 29 and 30 in the Old Testament).
He does this because He has revealed Himself as a personal God, not a vague "force", or a god who inhabits all living things, which would make him different in all beings. In fact, He has a name. Several, actually; the most common being "Yahweh". Somewhat like us when we name our pets, He has even named the stars. We read in the Old Testament book of Isaiah, chapter 40, verse 26: "Lift up your eyes on high and see who has created these stars, the One who leads forth their host by number, He calls them all by name;..."
Being thus a personal being, He has a specific personality. He has emotions, a will, an intelligence, and standards for right and wrong. While He exists independently of man, He has made man in His image, as the being He treasures most. This infinite God from eternity past also actually loves this finite, fickle, creation of man. This is really a pretty staggering thought. We read this in Psalm 8: 3 -- "When I consider Your heavens, the work of Your fingers, the moon and the stars, which You have ordained; what is man that You take thought of him, and the son of man that You care for him?'"
There is no support in the Bible for the existence of extra-terrestrials. Hebrews 2: 7,8 say: "You have made him for a little while lower than the angels; You have crowned him with glory and honor, and have appointed him over the works of Your hands; You have put all things in subjection under His feet." In the New Testament we see that God sent His Son for a vital purpose, one dear to His heart, the redemption of mankind. Jesus wasn't sent to die for the forgiveness of sins for animals or space aliens.
As part of His intervention in the course of nations, He raises up rulers and disposes of them at will. For example, in the Old Testament book of Jeremiah 27: 6, 7 we read "Now I have given all these lands into the hand of Nebuchadnezzar king of Babylon, My servant, and I have given him also the wild animals of the field to serve him. All the nations shall serve him and his son and his grandson until the time of his own land comes; then many nations and great kings will make him their servant." Nebuchadnezzar was a heathen king, not initially a believer in Yahweh, but was literally putty in the hands of God. Many other examples of God intervening in the course of nations can be found in the Bible.
He establishes nations and individuals for His purpose. In the New Testament book of Acts, chapter 17, verses 26 and 27, we read, "...He made from one man every nation of mankind to live on all the face of the earth, having determined their appointed times and the boundaries of their habitation, that they would seek God, if perhaps they might grope for Him and find Him, though He is not far from each one of us;..."
A logical question to ask would be, are these stories really true? Do we have any proof that these people of long ago existed? There are many examples of the historical reliability of the Bible by archaeology. Nelson Glueck, a Jewish archaeologist, wrote in his book Rivers in the Desert; History of the Negev, Jewish Publications Society of America, 1969, "It may be stated categorically that no archaeological discovery has ever controverted a biblical reference." Just a very few of the ways archaeology has confirmed biblical accounts of rulers, nations, and cities have been the excavation of the Elba tablets in Syria in 1964, confirming the existence of Sodom and Gomorrah in Genesis; and Publius, a ruler of Malta (we read about him in the book of Acts, chapter 28) which we see confirmed in excavations as reported by F. F. Bruce, "Archaeological Confirmation of the New Testament", from Revelation and the Bible, Grand Rapids: Baker Book House, 1969.
While this will not prove to all people that God does intervene in the courses of nations, we have good reason to believe that the nations, cities, and individuals cited in the Bible did exist. Indeed, history backs up the Bible more than any book of ancient literature. Finally, simply look at how nations have fared according to how they have denied or followed God. The basic history of nations will show if they have been blessed or cursed according to how God says He will deal with them. For example, which nations have produced the most important inventions, and progress in science and medicine? Where did penicillin, anesthetics, organ transplants, the telegraph, electric lights, microwave ovens, radio, computers, telephones, trains, airplanes, weather satellites and many other advances come from? Christian nations that obeyed the God of the Christian Bible!
There are countless cases of God intervening in the lives of individuals in the Bible. In fact, He knows us and has a plan for our lives before we are born. In Psalm 139:16 we read, "Your eyes have seen my unformed substance; and in Your book were all written the days that were ordained for me, when as yet there was not one of them." That passage also tells us that human life begins in the womb.
God not only intervenes in the lives of nations and men, but He had a special purpose in the founding of the United States, as other articles in this website will show. And it was because of His purpose and our status before Him that He had a special role in 9/11. To understand more of His role in 9/11, click on How Did America Begin?
