Preposition phrase modifying part of the group but not all?

Hi. Please look at the examples and also the comments I made, and tell me what you think.

1) XXX came about as a result of 1) understanding, 2) believing, and 3) marveling in the gospel.

I think to form a phrase like the underlined one, the prepositional phrase 'in the gospel' should go with the three words 'understanding', 'believing' and 'marveling'. And I can see how the two 'believing' and 'marveling' go with the phrase 'in the gospel' because I think we usually use them together like 'believing in the gospel' and 'marveling in the gospel', but I feel/think 'understanding' doesn't go with the phrase. Thus I think I can say the sentence is at best awkwardly constructed. What do you think?

2) We are glad to inform you that we will offer 1) free admission and 2) dinner at our seminar.

My question on this sentence is basically the same as the first one: I feel the prepositional phrase 'at our seminar' goes with 'dinner' but not necessarily with 'free admission'.
