Raising kids in a godless culture - strategies?

Feel like I'm constantly swimming upstream trying to raise my kids with Christian values when everything around us is pushing the opposite direction. School, friends, social media, TV, everything. I'm not trying to shield them completely because they need to function in the world, but I want them grounded in faith. We do church, family devotions, I talk about our faith but I wonder if it's enough. What are you guys doing that's actually working?
