It is easy to look like a thriving Christian on the outside while slowly dying on the inside. Jesus had a direct and sobering message for the church in Sardis, and it is just as relevant today. Here is what it means to strengthen what remains in your spiritual life.
What Did Jesus Say to the Church in Sardis?
In Revelation 3:1-6, Jesus addresses a church that had a strong reputation but a serious problem beneath the surface. He says plainly, “I know your works. You have the reputation of being alive, but you are dead.” – Revelation 3:1 (ESV) Sardis was literally known as a “necropolis,” meaning death city. People buried their dead on its hills, hoping a local God would restore them to life. Jesus used that backdrop to describe a church that looked alive but was spiritually hollow. The warning is clear. Some people are more invested in their reputation than in their actual relationship with Jesus Christ.
How Do You Know If You Are Spiritually Dead?
Spiritual deadness does not always look dramatic. It often looks like going through the motions, serving out of guilt, or keeping up appearances while feeling empty inside. Jesus told the church in Sardis that their works were incomplete in His sight. Every Christian will go through dry seasons. It is part of human nature to drift. The danger is staying there and never heeding the wake-up call.
Four Ways to Strengthen What Remains in Your Faith
1. Rely on the Holy Spirit
Jesus opens His message to Sardis by identifying Himself as the one who holds the seven spirits of God. This is a reference to the sevenfold ministry of the Holy Spirit, drawn from Isaiah 11:2: “And the Spirit of the Lord shall rest upon Him, the Spirit of wisdom and understanding, the Spirit of counsel and might, the Spirit of knowledge and the fear of the Lord.” – Isaiah 11:2 (ESV) These are not just poetic descriptions. They are real resources available to every believer. Spirit of the Lord: The presence of Christ living in you Spirit of Wisdom: Guidance for decisions and discernment Spirit of Understanding: Clarity in confusing seasons Spirit of Counsel: Direction when you do not know which way to go Spirit of Might: Supernatural strength and boldness Spirit of Knowledge: Deeper understanding of God’s Word Spirit of the Fear of the Lord: A reverence and awe for who God is Many Christians are running on empty because they are not actively asking the Holy Spirit to fill them. This is not a one-time event. Just as a car needs fuel, believers need to be continually filled. D.L. Moody once said he needed to be constantly filled with the Holy Spirit because He leaked. That is true for all of us. If you are weary, worn out, or feel like you do not have what it takes to keep going, the answer is not more effort. It is more of the Holy Spirit.
2. Wake Up
Jesus says directly in verse 2, “Wake up, and strengthen what remains and is about to die, for I have not found your works complete in the sight of my God.” – Revelation 3:2 (ESV) There is no cruise control in the Christian life. Spiritual sleepwalking is real, and it is dangerous. When we are more focused on what others think of us than what God thinks of us, we are on a path toward spiritual death. Maintaining a spiritual facade is exhausting. It requires constant effort under your own power, and it leaves no room for honesty before God. If the Holy Spirit is nudging you right now, that is not condemnation. That is grace. That is God issuing a wake-up call because He has not given up on you.
3. Remember, Keep It, and Repent
In verse 3, Jesus says, “Remember, then, what you received and heard. Keep it, and repent.” – Revelation 3:3 (ESV) There was a time when the gospel felt fresh and alive. There was joy, excitement, and a sense of wonder at what Jesus had done. Jesus is calling the church in Sardis, and us, back to that place. David captured this longing in Psalm 51 after his own spiritual failure. He did not ask for a new faith. He asked for the joy of his salvation to be restored. Sometimes the most powerful thing you can do is go back to the basics. Strip everything else away and return to the simple truth that Jesus came to die in your place, take your sin upon Himself, and give you eternal life. Jesus also adds a serious warning. He says if you will not wake up, He will come like a thief, and you will not know the hour. This is not meant to create fear for its own sake. It is meant to create urgency. Do not put off what needs to happen today.
4. Walk with Jesus Daily
In verse 4, Jesus says, “Yet 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.” – Revelation 3:4 (ESV) Walking is a symbol of daily living. Strengthening what remains is not about a single dramatic moment. It is about trusting Jesus with each day, each decision, and each season. The white garments mentioned here are not something the faithful people earned. White is a symbol of purity, and Jesus is the one who makes us pure. He takes our soiled garments and replaces them with His righteousness. We walk in purity not because we are capable of it on our own, but because He has made us clean through His blood.
What Is the Book of Life and Why Does It Matter?
The Book of Life is mentioned seven times in Revelation. It is the record in heaven of every person who will spend eternity with God. When you accept Jesus Christ, your name is written in it. But Jesus gives a sobering warning in verse 5. He promises that those who overcome will never have their names blotted out. The implication is clear. For those who refuse to wake up, who continue living a spiritual double life without repentance, that name can be removed. To those who do overcome, Jesus makes three promises. They will be clothed in white garments. Their names will remain in the Book of Life. And Jesus Himself will confess their names before the Father. That is worth waking up for.
Life Application
This week, take an honest inventory of your spiritual life. Not what it looks like to others, but what it actually looks like before God. If you have been coasting, going through the motions, or relying on your reputation rather than your relationship with Jesus, this is your wake-up call. Choose one specific way to invite the Holy Spirit into your daily routine this week. It might be a few minutes of prayer in the morning asking Him to fill you with wisdom, strength, or counsel. It might be returning to a habit of reading Scripture that you have let slip. Whatever it is, take one step back toward walking with Jesus daily. Ask yourself these questions as you reflect: Am I more concerned with how my faith looks to others than with how it actually is before God? When did I last feel genuinely alive in my relationship with Jesus, and what has changed since then? Am I relying on my own strength to live the Christian life, or am I actively asking the Holy Spirit to fill and empower me? Is there an area of my life where I need to repent and return to what I first received and heard?
