We must be free not because we claim freedom, but because we practice it.

The line frames freedom as an achieved condition rather than a merely asserted right: liberty is sustained through habitual action—speaking, choosing, associating, dissenting—rather than through slogans or formal claims. It implies that political or social freedom can atrophy if people do not exercise it, and that authentic liberty is demonstrated in conduct, not rhetoric. Read this way, the quote also carries an ethical challenge: individuals and communities must embody the responsibilities of freedom (courage, self-restraint, respect for others’ agency) if they want freedom to be real and durable. The emphasis on “practice” suggests freedom is a discipline—something enacted daily and collectively.
