Since the beginning of time, there have been portals and attempts to create them. This truth is why Nimrod—and human beings since the Tower of Babel generation—have been trying to pry open portals. The most common belief is that ONLY benevolent, friendly spirits enter our dimension through opened portals. However, the Word of God makes it clear that not only can benevolent, friendly angelic spirits enter through opened gateways but also so can malevolent, unfriendly demonic spirits. Indeed, because Satan can appear through an open portal looking like an angel of light, God wants mankind to know they really don’t know what will come through any portal human beings have opened.
Twenty-first century’s human beings definitely are technologically competent to do whatever they imagine to do. This truth is ever-so evident wherever there are human enhancement experiments (genetic manipulations), and evident wherever present-day scientists are searching for interdimensional portals (seeking time travel)—the former of which is happening in laboratories all over the world; the latter is happening primarily in CERN near Geneva, Switzerland.
Most Christians are not aware that there is not going to be a Revived Roman Empire; therefore, they are also unaware of the fact the last successive empire that came against Israel is the Ottoman/Turkish/Islamic Empire, and that this is the empire that will be revived. Moreover, the Islamic religion of this revived empire is really a system of government, which relies on Mystery Babylon (oil/pitch) . . . from that Great Harlot (city). She not only sits on seven kingdoms (gets nations drunk with her wine) but also she sits on the seven hills of Mecca!
