Why is knowing Jesus Christ important for Christians?

Peter's assurance in the face of imminent death stemmed from his intimate knowledge of Jesus Christ. This is illustrated in the narrative of Acts 12, where Peter, despite being chained and condemned, sleeps soundly because he knows the Christ who saves. Knowing Jesus means understanding His character, His work of salvation, and His authority over all elements of existence. It transforms fear into faith and strengthens believers under pressure. The experience of knowing Him is not merely intellectual; it is relational and experiential, where one realizes that faith in Christ brings peace amid chaos, assurance in uncertainty, and hope for the future.
