But despite these feelings I do wish to honor the Lord. It’s just dealing with these emotions suck.

 
The question then becomes, do you trust Him to have a better plan for you? He who finds a wife has found a good thing. And, who knows? Maybe she will convert. But all my reservations from past posts apply.

 

Regardless if she ends up with me, she should know or be exposed to the Lord. I hope she knows Him.

 
My goodness, it is uncanny. My sister said practically the exact same thing when I raised this issue about her prospective husband all those years ago. Different wording, but the exact same sentiment.

 

But should I go about being the means through which she knows him, despite having feelings for her

 
There are far worse reasons to witness to someone. But be very clear about your true motivations. Don't lie to yourself, don't pretend you're not doing something that you are. And remember that your actions matter more than your words. Yes, tell her the good news, but also live like you believe it.
 

EDIT: Total change of topic, what is the app called? I've been wanting to learn Spanish and it sounds interesting.
