Then He called His disciples and said to them, "Truly I tell you, this poor widow has put in more than all those who are contributing to the treasury. For all of them have contributed out of their abundance; but she out of her poverty has put in everything she had, all she had to live on."
Mark 12: 43-44
All? Not just your money, but all? Your family, friends, job, health, home, books, internet, music, etc., etc., etc.? What really struck me here was not just all she had, but, in particular, to live on. In some ways all these things are not just possessions, but sustenance. We live on them.
