Death is always watching. Always waiting.
Life is slowly eroding away from your brain and heart.
Then comes death, to take you away.
This is life. A circle that will end one day. The sun will go white, instantly killing all life and destroying the Earth, if it still exists. Wars will happen. People will die. We will die. Death is not to be feared though. We will reach the holy land, and we will watch our loved ones from up above.
When Jesus comes back, that is the true end of the world.
