Believing takes practice.

In L’Engle’s spiritual imagination, belief is less a one-time intellectual assent than a lived discipline—something strengthened through repeated acts of trust, attention, and fidelity. “Believing takes practice” suggests that faith (religious or otherwise) is learned the way skills are learned: by doing, failing, returning, and persisting. The line also implies that doubt and fluctuation are normal; practice exists because steadiness does not come automatically. Read broadly, it reframes belief as an active verb—choosing to lean into meaning, hope, or love even when certainty is unavailable—rather than a static possession one either has or lacks.
