If we believe in God, than we believe that everything that happens, happens because of God, and as God is good, we must say that it’s only a lack of understanding, why, for example there is so much pornography, there is evil in this world; but we must say, that there is a reason, a positive reason why it’s happening; ironically, by getting upset, that’s exactly what the satan wants, because anger is what gives us the motivation to be the satan, to be evil, which is why all people whom are evil, are angry and justify it.
