Thy Strong Word — Revelation 3:1-13: Apocalypse—A Revelation to Sardis and Philadelphia

Sardis and Philadelphia, Asia Minor—Jesus is delivering critical messages to the churches in Sardis and Philadelphia. To Sardis, He warns of their reputation for being alive while being spiritually dead, urging them to wake up and strengthen what remains. To Philadelphia, He offers praise for their perseverance and promises an open door that no one can shut. Are we spiritually awake and attentive to God’s opportunities in our lives?

The Rev. Dr. Matthew Heise, Executive Director of the Lutheran Heritage Foundation, joins the Rev. Dr. Phil Booe to study Revelation 3:1-13.

Shrouded in mysterious visions of cosmic battles, plagues, and catastrophic events, the Apocalypse of St. John, or as it’s more commonly known–the Book of Revelation, paints a haunting picture of the end times. Cryptic symbols of beasts, the rise of the Antichrist, and the final judgment unfold with unsettling intensity, revealing the ultimate clash between good and evil. Yet, beneath its terrifying imagery, Revelation is also a deeply personal letter, offering comfort to early Christians facing persecution. It reassures them—and believers today—of God’s control over history, His promise of redemption, and the certainty of Christ’s victory.

Thy Strong Word, hosted by Rev. Dr. Phil Booe, pastor of St. John Lutheran Church of Luverne, MN, reveals the light of our salvation in Christ through study of God’s Word, breaking our darkness with His redeeming light. Each weekday, two pastors fix our eyes on Jesus by considering Holy Scripture, verse by verse, in order to be strengthened in the Word and be equipped to faithfully serve in our daily vocations.

Revelation 3:1-13

To the Church in Sardis

3 “And to the angel of the church in Sardis write: ‘The words of him who has the seven spirits of God and the seven stars.

“‘I know your works. You have the reputation of being alive, but you are dead. ²Wake up, and strengthen what remains and is about to die, for I have not found your works complete in the sight of my God. ³Remember, then, what you received and heard. Keep it, and repent. If you will not wake up, I will come like a thief, and you will not know at what hour I will come against you. ⁴Yet you have still a few names in Sardis, people who have not soiled their garments, and they will walk with me in white, for they are worthy. ⁵The one who conquers will be clothed thus in white garments, and I will never blot his name out of the book of life. I will confess his name before my Father and before his angels. ⁶He who has an ear, let him hear what the Spirit says to the churches.’

To the Church in Philadelphia

⁷“And to the angel of the church in Philadelphia write: ‘The words of the holy one, the true one, who has the key of David, who opens and no one will shut, who shuts and no one opens.

⁸“‘I know your works. Behold, I have set before you an open door, which no one is able to shut. I know that you have but little power, and yet you have kept my word and have not denied my name. ⁹Behold, I will make those of the synagogue of Satan who say that they are Jews and are not, but lie—behold, I will make them come and bow down before your feet, and they will learn that I have loved you. ¹⁰Because you have kept my word about patient endurance, I will keep you from the hour of trial that is coming on the whole world, to try those who dwell on the earth. ¹¹I am coming soon. Hold fast what you have, so that no one may seize your crown. ¹²The one who conquers, I will make him a pillar in the temple of my God. Never shall he go out of it, and I will write on him the name of my God, and the name of the city of my God, the new Jerusalem, which comes down from my God out of heaven, and my own new name. ¹³He who has an ear, let him hear what the Spirit says to the churches.’

Rev. Dr. Phil Booe

Native North Carolinian Rev. Dr. Phil Booe serves pastor of St. John Lutheran Church of Luverne, MN, and host of Thy Strong Word on KFUO Radio. His parishioners probably think he can’t teach Bible study without a mug of coffee in his hand, and he’ll always be happy to eat a plate of sushi. When he’s not shepherding his flock or teaching on the radio, you might find him watching bad movies from the 50s, 60s, and 70s, and especially binging RiffTrax and MST3K episodes. Some day he’d love to travel to the Lutheran homeland in Germany, but for now he spends time in Minnesota with his wife, son, daughter, and cat, and looks forward to Holy Week every year.
