That sounds really exciting and I think it’s great that you’re bold and brave enough to step out and represent Him. Your comment reminded me of when I was in high school in the UK and I set up a weekly Christian Union meeting. I think I was the only Christian in my besthookupwebsites.org/tr/wildbuddies-inceleme school and students only came for the food to begin with but we had different drama groups and visitors come in and we drew a good little group.
You could try the free online preaching course to give you the basics of preaching effectively. I’d say it’s not just about communicating but connecting.
