Verses 6-21 of Revelation 22 form the epilogue to the book. In these concluding verses, the Bible comes full circle. It opened with the promise of a coming Savior, who would redeem is people from their sins. That promise, which came immediately after the fall of Adam and Eve, is recorded in Genesis 3:15. Then the Bible ends with the promise of Jesus’ second coming. His final invitation for salvation comes in 22:17. He once again identifies Himself, and provides the incentive to respond to Him.
