The sun shall be turned into darkness, and the moon into blood, before that great and notable day of the Lord come:

ACTS 2:20KJV
Know the Bible

What does Acts 2:20 mean?

Acts 2:20 describes a dramatic sign: the sun will become dark and the moon will appear red like blood before the arrival of the “great and notable day of the Lord.” This verse points to extraordinary events that signal a significant moment in God’s plan.

Peter is speaking to a crowd in Jerusalem during Pentecost, quoting the prophet Joel to explain the unusual happenings they are witnessing. By mentioning these cosmic signs, Peter is showing that what the people see and hear is part of a much larger story about God’s actions in history, especially as it relates to the coming of the Messiah and God’s final purposes.

The Greek behind Acts 2:20

  • “Sun” (ἥλιος, hēlios) and “moon” (σελήνη, selēnē): These words refer to the literal sun and moon, but in prophetic language, they often symbolize major changes or upheavals.
  • “Turned” (μεταστραφήσεται, metastraphēsetai): This Greek word means to be changed or transformed, emphasizing a sudden and striking shift in the natural order.
  • “Darkness” (σκότος, skotos): This word means darkness or obscurity, often used in the Bible to describe times of judgment or crisis.
  • “Blood” (αἷμα, haima): Here, “blood” describes the moon’s appearance, likely meaning it looks red, which can happen during a lunar eclipse or in certain atmospheric conditions. It signals something alarming or out of the ordinary.
  • “Notable” (ἐπιφανῆ, epiphanē): This word means something manifest, glorious, or clearly seen. It highlights the day as one that will be unmistakable and significant.

Why Acts 2:20 matters

  • Acts 2:20 helps clarify that the early Christians saw the events at Pentecost as part of a bigger prophetic picture, not just a random miracle.
  • The verse emphasizes that God’s actions in history are often marked by signs in creation, drawing attention to moments of great importance.
  • Understanding this verse in context shows how Peter connects the life and work of Jesus to ancient promises, helping his listeners see continuity between their Scriptures and what is happening in their own time.
