What did Jesus mean by "the end of the age" in Matthew 24? Is it the same as the Day of the Lord, and how does it relate to the Rapture, the Second Coming of Christ, and God's final judgment? In this in-depth Bible study, we examine Jesus' answer to the disciples' questions in the Olivet Discourse and compare it with key passages from Matthew 13, 1 Thessalonians 4–5, 2 Thessalonians 2, 2 Peter 3, and Luke 17. By comparing Scripture with Scripture, this lesson presents a biblical framework for understanding one of the most significant prophetic themes in the New Testament.
