Your stuff (all the things you own) is either aiding you in becoming the person you want to be, or it is an impediment to you in that pursuit.
If it is an impediment, then get rid of it. If it is an aide, then keep it.
Consider the Rich Young Man, and the passages dealing with laying up treasure in heaven for transcendent application.
Note: This does not come easy to me, but I hope I am learning from my wife’s good example.
