I found this reading difficult to understand too Patricia.
I tried to find a good Catholic commentary on it but to no avail but the line that stood out for me was where our Lord says, "for the sons of this world are more shrewd in dealing with their own generation than the sons of light."
For me that explained much what the story was all about.
Worldly people will devise and scheme in so many ways to make sure that their temporal affairs are provided for and even be commended for their shrewdness in doing so while the children of God, even the most enlightened can be so lax in providing for things pertaining to their eternal salvation.
If we put the same effort into caring for our souls as we do in caring for our bodies, then we'd be all walking saints on earth.
What is meant by this? And I tell you, make friends for yourselves by means of unrighteous mammon, so that when it fails they may receive you into the eternal habitations.
I think this would be referring to money and it's use. Even though money is a tainted thing it can be turned to good when used for good. For example if I helped the needy with whatever extra I had or better still from what little I had, then no doubt the needy will be there to welcome me into eternal life and plead for mercy on behalf.
But I wonder if I'm doing enough to qualify.
