Evils have such powers and thus uses it for all of his benefits. He wants us to be his believers and he is winning. We are letting him win. We are blinded by his power. We know what evil want us to know. Even I as a believer of God sometimes doubt that how can this be this if God is real. How can a person(astrologers) predict our future and can be true. How that if a person of hindu religion prays to the hindu God that he may success in life and he triumphs? We all have that doubt. But I just want to say that if you believe God from your true heart you can never get diverted by these things. Evil blinds us by these things. He do not want us to see the truth. Just we need to be strong enough to defeat the evil.
