Yes, many philosophical and spiritual views suggest suffering is integral to the human condition, fostering resilience, empathy, depth, and appreciation, while people without it might lack maturity, connection, and perspective, existing in a shallower, less complex state, though some theorize they’d be more carefree but perhaps underdeveloped.
We suffer because of sin so yes; it is a necessary part of human life. I don’t know what it would be like if there were no more suffering, but I can only imagine it would have to be a much better place to be in the mind and body.
I do not believe so, if no one suffered, everyone would have a “perfect” life. I know wealthy people who suffer from being lonely. I know poor people who suffer not having food to eat. I know wealthy people suffering from cancer. I know poor people who suffer from cancer and have no way paying for life saving treatments. We all suffer at some point, some more than others.
Man if there was a way to not suffer most of us who have suffered, would probably say they would love to know what way, without a second thought. However, without suffering there would be no compassion, empathy, unfortunately….and possibly even lack if real love. Any thoughts?
