Never be afraid to trust an unknown future to a known God.

The saying urges confidence in divine providence when the future feels uncertain. By contrasting an “unknown future” with a “known God,” it frames faith as a stable relationship or character-knowledge—God is understood as trustworthy even when circumstances are not. In devotional terms, it functions as counsel against anxiety and paralysis: one can act, endure, and hope without needing full foresight. The line is frequently associated with Corrie ten Boom’s Christian witness—especially her postwar ministry shaped by suffering and forgiveness—so readers often hear it as hard-won reassurance rather than abstract optimism.
