Correct. There's one Sunday devoted to the readings about Jesus's statement that getting to heaven is like passing through the "eye of the needle", a very narrow gate to a city. The standard interpretation is that to pass through the eye of the needle, you need to remove all of your belongings. In other words, you can't take it with you.

It is fairly common for preachers to say that money is not the problem -- it's what you do with the money.
