There is a well-known story of Jesus encountering a rich man who wanted to enter the kingdom of heaven. And Jesus told him to sell all his possessions and give them to the poor. (See Mark ch. 10). Now I don’t think Jesus was telling us that we need to sell all of our “stuff” and give to the poor. He merely recognized the attachment of that man to his riches and knew that it was an impediment to his spiritual welfare. I have known of people who have taken a vow of poverty and given everything away. I’m not inclined myself! I like my stuff. However, I am more conscientious about non-attachment to my “stuff” and have made an effort to be more generous in my day to day life.
I heard someone point out one time that anyone who is miserly with his money (and stuff) is also going to be miserly with his heart.
