An important practical possibility:
Here’s a way to ‘leave all our possessions’ = put it in common use for others to share in it.
For example, allow others to share your food, clothing, money, computers etc… or even your house and car but with “wisdom” (i.e. To those really needing it and not toward opportunists or exploiters).
It’s not my opinion or anything like that since the verse below proves that this is how the earliest (‘first church’) of “all believers” (not ‘some believers’) was:
“All the believers were together and had everything in common.” (Acts 2:44)
Any true gathering/group/church of believers in Christ are thus required to do ‘likewise’.
