There is a spiritual war happening across the entire world between good and evil. Good being the truth of Torah and evil being all false belief systems. We need to understand that we are at war and we are soldiers of Hashem. The teachings of our forefathers and our Sages are our weapons in this war.
"...The Jewish people are duty-bound to clarify for themselves and proclaim to the world that the confrontation between themselves and Ishmael is between the G-d of Israel and the false religion called Islam. The confrontation of the redemption era must constitute a collision between our G-d and theirs. Then G-d’s victory will be the height of Kiddush Hashem and proof of His greatness and unparalleled might, and will establish His reign over the world.
Should a frightened coward whisper to you that such a proclamation is likely to heap tragedy and destruction upon the Jewish People, send him back where he came from. Do not let him spread his fear. Surely, it is Israel’s duty to sanctify G-d’s name and make the world understand that “the L-rd is G-d”; there is none besides Him” (Deut. 4:35). Whoever has reservations about this and intentionally ignores his duty out of fear, letting the false religions rule the world, profanes G-d’s name and is partner to blasphemy.
Surely the false religions are undeterred from proclaiming their “truth”. Neither Christians nor Moslems fear confrontation with other religions, and they demonstrate their views publicly, aggressively trying to reach and convert members of other faiths, including the Jewish People—Heaven help us. The Ishmaelites speak openly about the greatness of their religion, never hesitating to talk of waging holy war for it’s sake.
By contrast, not only do a lion’s share of Jews, including the impoverished regime in Eretz Yisrael, reject the truth of Torah, but they allow the false religions to influence our Jewish brethren to change their faith, and do not deport them form the Holy Land. Our policy must be to demonstrate that the confrontation is and will remain religious, a struggle between G-d and the god of the nations, between G-d’s Torah and alien culture and beliefs. That they find the very thought of this illegitimate, insane and abominable, is our main problem. For the Ishmaelites’ pious faith, in face of Jewish heresy and apathy, we will ultimately pay a heavy price – Heaven help us!"See more @ The Key to Redemption: Rabbi Kahane On The Era of Redemption.
