One of the ways I try to do this with my kid, is to try to investigate what's behind what we see and interact with -- with technical stuff it's asking how it works and how things fit together, with social stuff it's asking what's going behind the scenes and getting involved with it. Then reflecting on how cool the technical thing or event/social machinery is and what function it serves. This has been generative of tons of great questions from my kid and great discussion with them.
IME churches and plenty of theologians stop at thought terminating cliches, like "faith is believing without seeing". I've had more satisfaction exploring mysteries by following the evidence and things that can be falsified.
