The reformation of our mind has much to do with the way we perceive God, His creation and above all the way we relate to Him in Spirit and in Truth. Dualism has been created as just the first stage. God had allowed Islam to take hold of the mind of many but only as a competition to Christian dualism as well as competition with Judaism.
No matter how one wants to interpret divinity, as far as the Bible is concerned everything spins around the Jew and the One God. As the biblical history portrays; God often used one nation, and a ruler, to unseat yet another and then that ruler was deposed by yet another ruler.
Islam is also dualistic and it can't get out of the quagmire of definitions as to what is good and what is evil. Quran does not address too many facets of human existence; hence, it is narrow and dogmatic, which also leads to fanaticism. Unlike Quran, the Bible was written by 40 authors and all of them address something central, but from different angels. This in turn does not breed fanaticism, but rather attracts rational mind. With this sort of a rational, unclouded by fanaticism or a blind belief mind we investigate God's truth and not our subjective beliefs, which often have been dictated by the founders of an organized religion.
The third alternative, the final one, is the Last Reformation of the human mind worldwide. All must know that God did not make Satan to war with, to oppose, or to give Satan or the devil (Greek diabolos) any sovereign powers. Any rebellion in heaven, which seduced ancients' mind, is not even possible and our God-given gift of logic and that of His Word explains it.
The idea that humans must be on the look-out for, or even fight with an interpreted-by-theology evil, is not the truth.
So, please get reformed today. Know your Creator the heavenly Father as He is truly.
IN PREPARTION FOR THE COMING OF OUR KING MESSIAH
[Isaiah 40:1] “Comfort, O comfort My people,” says your God.  “Speak kindly to Jerusalem; and call out to her, that her warfare has ended, that her iniquity has been removed, that she has received of the LORD’S hand double for all her sins.”  A voice is calling, “Clear the way for the LORD in the wilderness; Make smooth in the desert a highway for our God.  “Let every valley be lifted up, and every mountain and hill be made low; and let the rough ground become a plain, and the rugged terrain a broad valley;  Then the glory of the LORD will be revealed, and all flesh will see it together; for the mouth of the LORD has spoken.” [Matthew 3:1-3] Now in those days John the Baptist came, preaching in the wilderness of Judea, saying,  “Repent, for the kingdom of heaven is at hand.”  For this is the one referred to by Isaiah the prophet when he said, “THE VOICE OF ONE CRYING IN THE WILDERNESS, ‘MAKE READY THE WAY OF THE LORD, MAKE HIS PATHS STRAIGHT!’”
These not physical valleys nor mountains but the doctrines of man that make no sense. Test it. And prove it yourself with the God given freedom. Be blessed.
