At one time, everything I owned fit into my Buick.
In 1994, I spent 10 days in Europe with just carry-on luggage.
Life is simple if you don't have so many things to worry about. Let it go. It's just stuff. Why are you keeping it? Broaden your focus and see that there are far more important things in the world than owning stuff. One of my favorite verses in the King James Bible is Genesis 45:20. "Regard not your stuff."
If your hand isn't open to let go of the thing you have, then your hand isn't open to receive the thing that God wants to give you.
The thing that is most valuable is not always tangible.
What are you going to give away today?
