CSG Book 7 treats small repeated acts as spiritually serious. First words in the morning, the first step outside, gratitude while eating, and maintaining inward orientation through the day are not presented as ornamental niceties. They are the liturgy of attendance.
That language helps because “liturgy” names a repeated pattern that trains love. The chapter’s claim is that no life is patternless. If a person does not consciously build God-centered micro-practices, some other center will write the routine by default.
This creates a strong bridge between devotion and habit formation. The habits are not the whole of faith, but they are the way faith becomes concrete enough to shape character. What the chapter calls etiquette, a modern reader could also call embodied spiritual defaults.
