The World Must End?

The World Must End?
Is it true that destruction of mankind will come? If true, then when is it happen? Many religion predict that human annihilation, the world destruction and judgment day will come at any time even when I wrote this blog.
The Christians believe that the judgment day sign are the black riders. There are four black riders that will bring much agony to mankind if my memory serves me correctly. Death, disease, war, and hunger, this is some of the catastrophe that will lead mankind to the end. Even in any religion such as Muslim believe that neither the catastrophe of the world soon come on Friday, during that day, no human nor the creation of Allah will escape from it. The angle will blew his horn once, means all living creature in this world become death, and then the angle blew his horn for the second time, means all living creature that already death comes alive in naked. During that judgment day, mankind will not know of their family, friends, or anyone just him or herself only.Such many religions say about the end of the world, but we must prepare for it. We cannot just sit here and do nothing. We all have religion, religion teach use how to prepare for that day and we must follow the rule of the religion to survive after the life at the world. The judgment day will determine where we should go, heaven or hell. As for the nonbeliever, you should think that everything happen has its own reason why it happens. Ask this to yourself, why is it that only this blue planet has life on it? Is there any life out there? If you skeptic about UFO, then you should ask this question to yourself.
