Actually I dont think it is required to sell everything or much just to be saved on death as you can be overseas and die before it is possible to go home to do so but we know bible says anyone can be saved but if rich one is required to share because he will have money with him always the bible says for the rich to be rich in good works willing to share that it is not required to sell everything but to share good part with those in need I dont know how much but is safe to give most and can work in business to keep for running business and share rest. But I think it may be is required to fulfill God will to be saved on death and to be blessed by God to sell all your possesions except what you need for your survival and can keep some now such as books for what you will use to serve God now.
One thing you can do is run an honest business that is environment-friendly, employ the poor to work for you and make sure they are compensated well enough, well above average compensation, the work is low stress, and they still have plenty of free time.
If you do that, you probably won't be able to afford an expensive house and expensive car, you won't be much richer than your employees but you'll be able to sustain them indefinitely.
Ironically in many high per-capita income countries in Europe, many small business are setup in such fashion from their tax, compensation laws, social welfare, and other benefits. And for that poverty is almost absent among their citizens.
It's far better to employ the poor in low/un skilled but easy jobs than just hand them out money. The result is far more positive to the poor.
I've seen it for myself when we used to have our family business the ran the business in such manner. Sadly we closed the business from bankruptcy, not because of above average income for our workers but from several huge problems we faced at the time, the pandemic, huge hospital bills from both parents getting sick at different times, and other problems. We actually ended up in debt and still in debt now even after selling most of our possessions.
You don't really need to give up many things. In order to make a living, holding a job, holding a business in the 21st century, many things have become basic necessities like a smart phone, car, even couple sets of nice clothes.
What might be considered excess perhaps is getting an expensive car when a 3x cheaper car would have done the job just the same. Some people would justify expensive cars cost less to maintain in the long term. NOT true in most situations. Maybe if you lived in a place where the roads are really bad, the more expensive SUVs or pickup trucks would last longer in these conditions without repair and may actually be cheaper to maintain in the long run (not guaranteed!). Ironically, there are used SUVs and pickup trucks too that are much cheaper compared to brand new ones.
I agree about saving that is buying only what would be enough to fill a need. Like our previous example, if you need a car, keep it simple and modest, avoid the temptation of buying something a lot more expensive. Even used cars are good option if you are adept enough at inspecting used cars. Forgo luxuries and leisure. Keep traveling to a minimum even if you can easily afford it. A simple watch and other accessories, not upgrading your phone every year. It's ridiculous what other people do like upgrade phone every year or as often as they want. It's seriously damaging to our environment. Sure, the smart phone industry creates a lot of jobs and feeds a lot of families but not everything that makes money is good. Sometimes, too much is too much. When society gives money the highest priority, calamity is just around the corner and almost literally now as the effects of climate change is now more pronounced than ever.
