Sermon: Spiritual Keys for Bold Living
Introduction: The Cry for Courage
Good morning. If I were to take a poll this morning and ask, “How many of you would like to live a bolder, more courageous life for Christ?” I suspect nearly every hand would go up.
We see boldness in the pages of the New Testament and we long for it. We read about Peter standing up on the Day of Pentecost and preaching with such power that 3,000 people were saved. We read about Stephen, facing down an angry mob with a face like an angel. We read about Paul, standing before kings and governors, fearlessly proclaiming the gospel.
And then we look at our own lives. The fear of speaking up for Jesus at work. The anxiety about what our friends might think if we live too radically for Christ. The hesitation to step out in faith when God calls us to something new. We feel more like the disciples in the boat during the storm—terrified—than the disciples in Acts, turning the world upside down.
So, what’s the difference? Is it that they were superhuman, and we are not? No. The good news this morning is that biblical boldness is not a personality type; it’s a spiritual possession. It is not mustered up from within; it is unlocked from above.
Today, we will uncover three spiritual keys for bold living from God’s Word.
Key #1: The Key of a Transformed Identity (Acts 4:13)
Our first key comes from the book of Acts. Peter and John have been arrested for healing a lame man and preaching about Jesus. They are brought before the same religious council that condemned Jesus to death. It’s a high-pressure, intimidating situation.
“When they saw the courage of Peter and John and realized that they were unschooled, ordinary men, they were astonished and they took note that these men had been with Jesus.” (Acts 4:13, NIV)
The council was astonished by their courage (or "boldness" in other translations). But notice the source. It wasn't their education—they were "unschooled." It wasn't their social status—they were "ordinary." The source of their boldness was their association: "they took note that these men had been with Jesus."
This is the first key: Your boldness is directly proportional to your intimacy.
Boldness doesn't come from trying to be brave. It flows from being in the presence of the One who holds all power and authority. When you spend time with Jesus, something rubs off on you. His confidence becomes your confidence. His authority becomes your authority. His mission becomes your mission.
You stop seeing yourself as just "you"—a weak, fearful, ordinary person. You start seeing yourself as someone who has been with the King of Kings. Your identity shifts from "I am a sinner trying to be good" to "I am a child of God, empowered by His Spirit, and commissioned for His purpose."
Application: You cannot live boldly for a God you barely know. The key to a transformed identity is consistent, daily time in His presence—in prayer, in His Word, in worship. When you know who you are in Him, you can stand boldly wherever He places you.
Key #2: The Key of a Filled Vessel (Acts 4:31)
Let’s continue the story. Peter and John are released, and they go back to their community. They don’t strategize or panic; they pray. And listen to what they pray for:
“Now, Lord, consider their threats and enable your servants to speak your word with great boldness.” (Acts 4:29)
They didn’t pray for the threats to be removed. They prayed for boldness to speak in spite of the threats! And how did God answer?
“After they prayed, the place where they were meeting was shaken. And they were all filled with the Holy Spirit and spoke the word of God boldly.” (Acts 4:31)
This is the second key: Your boldness is supernaturally supplied by the Holy Spirit.
In Acts 1:8, Jesus said, “But you will receive power when the Holy Spirit comes on you; and you will be my witnesses…” The Greek word for "power" here is dunamis—the root of our words "dynamic" and "dynamite." It’s an explosive, supernatural power for a specific purpose: to be His witnesses.
Boldness is not self-help; it’s Spirit-help. The Holy Spirit is not a gentle whisper meant only for your private comfort; He is a raging river of power meant to flow through you into a dry and thirsty world.
You see, an empty vessel cannot give anything. A vessel filled with the Holy Spirit cannot help but overflow with courage, conviction, and power.
Application: Are you running on empty? You need to be continually filled with the Spirit (Ephesians 5:18). This happens through surrender. It means daily saying, “Holy Spirit, I yield my tongue, my will, my fears to you. Fill me afresh today and give me the boldness I lack.”
Key #3: The Key of an Eternal Perspective (2 Corinthians 4:16-18)
Our final key addresses the greatest enemy of boldness: fear. Fear of rejection, fear of failure, fear of pain. The Apostle Paul gives us the ultimate antidote.
“Therefore we do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day. For our light and momentary troubles are achieving for us an eternal glory that far outweighs them all. So we fix our eyes not on what is seen, but on what is unseen, since what is seen is temporary, but what is unseen is eternal.” (2 Corinthians 4:16-18)
This is the third key: Your boldness is sustained by fixing your eyes on eternity.
Paul calls his troubles—which included beatings, shipwrecks, imprisonments, and starvation—“light and momentary.” How? Because he was comparing them to the "eternal glory that far outweighs them all."
When your perspective is limited to this life, your risks feel enormous. "What if I lose my friend? What if I miss that promotion? What if people mock me?"
But when you live with an eternal perspective, your calculus changes. The worst thing the world can do to you is temporary. The best thing God has for you is eternal. This truth liberates you to be bold. You realize you have nothing to ultimately lose and everything to eternally gain.
You can boldly share your faith, because the potential of someone gaining eternity with Christ outweighs the temporary discomfort of rejection.
You can boldly obey God in your finances, because heavenly treasure is better than earthly security.
You can boldly endure suffering, knowing it is producing a glory you cannot yet imagine.
Application: Where are your eyes fixed? On the temporary problems, or the eternal promise? Cultivate an eternal perspective by regularly reading Revelation 21-22, meditating on Heaven, and asking God to make the reality of eternity more real to you than the fears of today.
Conclusion: Unlocking the Door
So, here are the three spiritual keys for bold living:
-
The Key of a Transformed Identity: Spend time with Jesus until His confidence becomes yours.
-
The Key of a Filled Vessel: Be continually filled with the Holy Spirit, the source of supernatural power.
-
The Key of an Eternal Perspective: Fix your eyes on the unseen, eternal glory that outweighs all temporary trouble.
These keys are not meant to be admired; they are meant to be used. You don’t need to muster up courage from your own depleted reserves. You have access to the limitless courage of Christ.
The door to a bold, impactful, world-changing life stands before you. It’s not locked because God is unwilling, but because we often try to kick it down with our own strength. Today, God is handing you these keys.
Take them. Use them. Unlock the door.
Let’s Pray:
Heavenly Father, we confess our fear and our timidity. We have tried to be bold in our own strength and have failed. Today, we receive the keys you offer.
We come to Jesus, asking that our identity would be rooted in Him. Fill us, Holy Spirit, with Your power and boldness right now. And give us eyes of faith to see our temporary struggles in the light of Your eternal glory.
We choose to step out in boldness this week, not because we are strong, but because You are. In the mighty name of Jesus, Amen.
