using a noun for adjective purpose

Question

Please excuse me for this question, but I want to know if I can use a noun as an adjective. For example, I want to say:

"I hold this mission close to my heart for its goodness."

Is this equivalent to saying:

"The mission is good that I hold it close to my heart."

But the latter sentence is not so appealing to me. I like the first sentence, but is it correct? That's my question.

Answer 1

The first sentence is correct. It explains that this mission is deeply important to you, and it explains why (its goodness).

I agree that the second sentence is awkward, and it also does not express the idea well. It would be better usage to say, "The mission is so good that I hold it close to my heart." But even this, though correct, is not phrased as well as the first one.
