In the grammar sections of my textbook, I learnt that

SENTENCE + ことになる

Expresses that SENTENCE has been decided.

However, in this context, it seems more like ことになる indicates that there is/was
a change of state.

> このように私たちが幸せな生活ができれば、私のゴールを果たしたことになります。  
>  "If we can all lead a happy life this way, it will be that I have achieved
> my goal."

If I regard なります as representing present tense, then I could imagine the
"decision" semantics working to a degree, but it would make less sense:

"If wen can all lead a happy life this way, I decide that I have achieved my
goal."

Again, since my textbook only taught me that ことになる expresses a decision, I
wanted to ask for clarification/confirmation in this case.
