We must use time wisely and forever realize that the time is always ripe to do right.

The line urges moral urgency: ethical action should not be postponed for a “better moment.” By pairing “use time wisely” with the claim that “the time is always ripe to do right,” it rejects excuses rooted in timing, convenience, or political calculation. The quote frames time as a resource that can be squandered through delay, and it treats justice as perpetually actionable—something that does not depend on perfect conditions. In Mandela’s broader public image, the sentiment aligns with a politics of principled perseverance: even under constraint, one can choose integrity and constructive action rather than waiting passively for circumstances to change.
