To make the world a better place by doing something meaningful with your life.
From a biblical perspective, this world is not our home. WE are put here because we are paying for our ancestors disobeying God blah blah blah.
Our aim is to try to get back to the Garden of Eden through making the world a better place and acknowledging God in our lives. Something like this.
Yes life is a punishment but at the same time it is a reward because we are taught that once we die if we live a good life we will be granted eternal happiness and an eternal life by God.
We are told that heaven will consists of only the good things in this life and even more. Just think of an eternal life full of only happiness and no evil people or things.
Yes life can be meaningless, but we can add meaning to it by believing in God and the afterlife and justice.
To be honest if i was not religious in some way I could understand why people take their life. IF you do not try to see the spiritual side of life and see this as all there is it is very easy to give up on life. Because life is crappy most of the time. YOu have to work. You have to deal with rude people everyday. You have to deal with your own parents dissapointing you etc. There is more heartache than joy in this life. Also the uncertainty of life makes us all anxious.
YOu just have to make the best of it and believe that there will be an eternal life after this full of only happiness if you live a good life.
This is the only thing that keeps me going.
Think of it. If there was no after life YES life would have no meaning and we could all just kill ourselves and finish it to just escape life. But it is the belief that there is an afterlife that keeps us going.
