Unlike most books of the Bible, Revelation contains its own title: “The Revelation of Jesus Christ” (1:1). “Revelation” (Gr., apokalupsis) means “an uncovering,” “an unveiling,” or “a disclosure.” In the NT, this word describes the unveiling of spiritual truth (Rom. 16:25; Gal. 1:12; Eph. 1:17; 3:3), the revealing of the sons of God (Rom. 8:19), Christ’s incarnation (Luke 2:32), and His glorious appearing at His second coming (2 Thess. 1:7; 1 Pet. 1:7). In all its uses, “revelation” refers to something or someone, once hidden, becoming visible. What this book reveals or unveils is Jesus Christ in glory. Truths about Him and His final victory, that the rest of Scripture merely allude to, become clearly visible through revelation about Jesus Christ (see Historical and Theological Themes). This revelation was given to Him by God the Father, and it was communicated to the Apostle John by an angel (1:1).
