On the official Star Wars site, Chirrut is described as "deeply spiritual" and a "warrior monk." A strong believer in the Force, which he treats almost like a religion, Chirrut has a peace that guides him, not unlike the Force. That said, his official character bio also explicitly states that "he lacks Force abilities." But that could mean that he just isn't strong enough, or connected enough, to use things like the Force Push in battle, not that he can't use the Force at all.
