The truth of the matter is that you always know the right thing to do. The hard part is doing it.

Robert H. Schuller (1926–2015), the televangelist and founder of California’s Crystal Cathedral, built his ministry around “possibility thinking”—a blend of evangelical exhortation and motivational psychology aimed at everyday decision-making. This line reflects the practical moral tone common in his sermons and popular books: he often framed ethical and spiritual growth less as a problem of ignorance than of follow-through, urging audiences to align actions with conscience and faith. The quote is frequently circulated in inspirational collections and attributed to Schuller in that broader self-help/sermonic context, though it is often repeated without a clear citation to a specific dated sermon or publication.

The saying separates moral knowledge from moral action. It claims that, in most ordinary situations, people are not genuinely confused about what is right; they are conflicted, afraid, tempted, or unwilling to pay the costs of doing it. The “hard part” is thus courage, discipline, and integrity—choosing the right course when it is inconvenient, unpopular, or personally costly. In Schuller’s characteristic style, the line functions as a call to personal responsibility: it removes the excuse of uncertainty and shifts attention to character formation and decisive action. It also implies that ethical living is less about discovering new principles than about consistently enacting the ones we already recognize.
