Sermon Summary: Great and Amazing, Just and True
(Revelation 15)

Main Idea

There is not an Old Testament God of wrath and a New Testament God of love. There is one holy God—great and amazing, just and true—who always saves His people and always judges sin. Revelation 15 brings these strands together in the Song of Moses and the Song of the Lamb, calling us to worship Him.

1. One God, Not Two (vv. 1–2)

• The God who sent plagues on Egypt is the same God who sent His Son to save the world.
• John sees another “sign in heaven”: seven angels with seven plagues that bring God’s wrath to completion.
• God’s wrath is not irrational or random—it is His settled, holy response to sin.
  • Orge: deliberate, reasoned wrath.
  • Thymos: boiling over, eruptive wrath.
• At the end of the age, God’s long patience reaches its end; His wrath will overflow against sin.

Application: Don’t pit God’s justice against His love. Both are perfectly united in His character and His actions.

2. The Song of Moses and the Song of the Lamb (vv. 2–4)

• John sees the martyrs and conquerors by a sea of glass mingled with fire, holding harps, ready to sing.
• They sing a united song—the Song of Moses (Exodus 15) and the Song of the Lamb (Revelation 15).
  • The Song of Moses: celebrated God’s deliverance of Israel through the Red Sea.
  • The Song of the Lamb: celebrates God’s ultimate deliverance through Jesus Christ.
• The same God who saved His people in the exodus saves His people through the cross.
• This song emphasizes God’s greatness, justice, truth, holiness, and worthiness of worship.

Application: Worship flows from remembering God’s mighty acts of salvation—past, present, and future.

3. God’s Wrath and God’s Glory (vv. 5–8)

• John sees the heavenly sanctuary—the tent of witness—opened. From it come seven angels with seven plagues.
• They receive golden bowls of God’s wrath from the living creatures around the throne.
• The sanctuary is filled with smoke from God’s glory and power, just as in Exodus when God’s glory filled the tabernacle.
• No one could enter until the plagues were finished.
• God’s wrath, like the plagues of Egypt, brings both judgment on His enemies and deliverance for His people.

Application: God’s glory is revealed both in salvation and in judgment. Both should move us to reverent worship.

Closing Thought

Revelation 15 reminds us that God’s story is one story—woven together from Exodus to Calvary to the final judgment. The Song of Moses and the Song of the Lamb declare the same truth:

• God delivers His people and defeats His enemies.
• God brings both salvation and judgment.
• Each person will receive one or the other.

Response: Will you meet Him as Savior or as Judge?
