Your life isn't in your possessions (or it shouldn't be)

What does God think about our stuff? If He isn’t calling us to give it all away (not necessarily), what is He asking?

When Jesus heard his answer, he said, “There is still one thing you haven’t done. Sell all your possessions and give the money to the poor, and you will have treasure in heaven. Then come, follow me.” (Luke 18:22)
