Ultimately these are questions that have no answers or at least no answers that can be definitive.  I have to come to my own conclusions about the meaning of life and living just like everyone else.  I try to see that for as many awful things in the world there are an equal amount of good things.  I try to see that for all the evil that men do there is plenty of good that men do as well.  I'm not sure if that's the case but plenty of people argue that there is an order to the world and everything in it.  Many take comfort in this even if it doesn't seem to be true but I want to know that all of it means something.  I want to know there's a reason behind it all and that everything will make sense.  I suppose it's all about finding purpose and meaning in something whether that's in people, religion, work, play, family...anything, really. Each man and each woman creates the essence (meaning) of his and her life; life is not determined by a supernatural god or an earthly authority, one is free. As such, one's ethical prime directives are action, freedom, and decision. In seeking meaning to life, the existentialist looks to where people find meaning in life, in course of which using only reason as a source of meaning is insufficient; the insufficiency gives rise to the emotions of anxiety and dread, felt in facing one's radical freedom, and the concomitant awareness of death. To the existentialist, existence precedes essence; the (essence) of one's life arises only after one comes to existence. With this in mind some have argued that life is full of absurdity and one must make his and her own values in an indifferent world. One can live meaningfully (free of despair and anxiety) in an unconditional commitment to something finite, and devotes that meaningful life to the commitment, despite the vulnerability inherent to doing so.
Life's purpose in Christianity is to seek divine salvation through the grace of God and intercession of Christ. The New Testament speaks of God wanting to have a relationship with humans both in this life and the life to come, which can happen only if one's sins are forgiven. Some sources ask the question:
Members of the scientific community and philosophy-of-science communities believe that science may be able to provide some context, and set some parameters for conversations on topics related to meaning in life. This includes offering insights from the science of happiness or studies of death anxiety. This also means providing context for, and understanding of life itself through explorations of the theories related to the big bang, abiogenesis and evolution. Science may or may not be able to tell us what is of essential value in life but some studies definitely bear on aspects of the question: researchers study factors that lead to life satisfaction, full engagement in activities, making a fuller contribution by utilizing one's personal strengths, and meaning based on investing in something larger than the self to find the answers.
People find their answers in different ways but ultimately they need it to be about something bigger and need to be able to draw some kind of sense out of it all.  I find it hard to limit myself to one view or one way of thinking over another.  I find it difficult to think there is only one answer to every question because there is so much in the world in terms of everything.  So much awfulness and goodness.  So much anger and love.  So much life and death.  It feels like there would have to be something keeping all of these things in order but maybe that's just my way of dealing with it all.  Maybe that's the only way we can cope with a world and with people that don't seem to make any sense the majority of the time.  I don't know if there's any way to make sense of everything but I know the attempt to do so is what matters.  I know that trying to make sense of it is the only way I'll ever be able to figure out what kind of world this is.  In the end, it really is a great odd comforting lonely fitting world.
