So life is meaningless according to you.
When this life is all you consider yourself to have, it is all the more precious to you. That I view my existence as temporary makes me value it all the more for the brief time I have, to the point that it alone has stayed my hand from killing myself on numerous occasions. No matter how bad things get, no matter how much pain I feel, at least it is SOMETHING rather than the void of complete nonexistence. Furthermore, I don't feel that lasting forever is necessary to make what I do while I am alive worthwhile or meaningful. To some, having an eternal afterlife would actually make it less meaningful, as there is no time constraint on anything, and even if that afterlife gives you free reign to do whatever you want, eventually, you will do all that you ever wanted many times over, and still have eternity to go. Basically, some people feel that they would lose all meaning if they did exist forever.
Personally, I would rather to exist without end, than have it cut short, but that is my personal feelings on the matter, and plenty of people do not feel that way.
Jesus Christ made truth claims about life explained the human condition and many things. Gave us his holy spirit which I experienced daily. The way he lived his life was authentic and I count him as an authority.
The statements attributed to him in regards to human nature are pretty shallow; the average person could see what he saw, even if they couldn't vocalize it very well.
valentine is there good and evil in life ???
I will answer, although this is not directed at me. Good and evil are concepts, with "good" normally being applied to what is considered beneficial to oneself and society without posing a detrimental consequence, and "evil" being that which harms oneself or others with little to no benefit to speak of. A "necessary evil" is knowingly doing something harmful, without better alternatives being present or reasonable to enact. Concepts do not physically exist, but are ideas, which can be subject to change. These concepts have changed drastically over time as societies have come and gone. Ultimately, they are subjective. Even if you believe that god established them, they would still be subject to that deity's outlook and experiences, and would be no less subjective.
