Every creature dies here on earth

We live in a mundane world. Once born, every creature dies here on earth. No one is immortal here. Even a lifeless thing would be completely destroyed one day in the faraway future. But a human being (even in a tiny creature) has an inner desire to live forever happily. This desire is not a matter of joke, but is based upon eternity; that is, each desire of a human being will surely be fulfilled in his/her afterlife if he or she can attain heaven not hell there. But there are some preconditions for being qualified for a heaven from the Creator. A wise human being must inquire about the preconditions to obtain a heaven. A person has a desire to get married to thousands of persons, but it is seemingly impossible here on earth. But it is my stanch belief that in our afterlife (in heaven but not in hell) we will be able to get married to innumerable persons. All of our unfulfilled desires will be smoothly implemented in our afterlife.
