Based on this definition:
"A passion is an intense drive that one has for a particular thing or activity. It consumes your thoughts during your down time if it's not your occupation. When people ask you what you're passionate about, you don't have to think about it."
I would still answer that my passions are:
God (and His Word), family, Music, home and garden and community outreach.
I have an intense drive for these particular things or activities and these are things that consume my thoughts and most of my time, the latter by design.
Are you sure you can't say with equal fervor that you are passionate about God, His Word and/or ministry? Your posts convey that.... It seems like on this thread that you're looking for a certain "feeling" and you've decided that you don't have that feeling about anything in your life, but I don't know if that's a good place to start with the analysis. Also, referencing your parents: if they've been married for 48 years and were good parents, I would say they are passionate about each other and passionate about you.
Passion isn't necessarily exhibited in flamboyant ways. A person who consistently and persistently pursues the same goals over the course of a lifetime is demonstrating that they are passionate about those goals. A person who stays loyal and true to the same people over the course of a lifetime is illustrating that they are passionate about those people.
If I were answering your acquaintance FOR you, based just on your posts on this forum and nothing else, I would say: "Yes, Bro. Robbins is passionate about God, God's Word, pursuing godliness...and a baby named Andrew and his family." You might say that you're not passionate about these things, but your "speech betrays you."
