God will leave nothing undone. As John continues to relate his heavenly vision, the unfolding story of Revelation is one of completion. When the harvest of God’s elect is ready to be gathered, Jesus will welcome every saint into His fold; when the hour of judgment arrives, God will answer the martyrs’ unresolved cry for justice; when the heavenly host observe God’s treatment of the righteous and the wicked, they will erupt with praise and adoration for His holiness, justice, and truth. Christians in all ages can take heart that God is at work and will not fail to accomplish His purposes.
