Three years they had sat under Jesus’ teaching. They watched Him heal, they listened as He taught in parables, they witnessed His death and resurrection. But it was not until the Spirit descended upon them that the veil lifted, and the full meaning of Jesus’ life, death, and resurrection came into focus.
What the Spirit Revealed
Acts chapter 3 offers a glimpse into this new clarity. Peter and John go up to the temple at the hour of prayer, and there they encounter a man lame from birth. Peter says to him, “Silver and gold I do not have, but what I have I give you: In the name of Jesus Christ of Nazareth, get up and walk!” (Acts 3:6, BSB). And the man, never having walked before, rises to his feet, walking and leaping and praising God. But as marvelous as the miracle is, it is Peter’s sermon that follows which reveals just how much the apostles now understood.
He speaks with a new confidence—not just boldness in tone, but depth in insight. He proclaims to the crowd that it was not by their own power or godliness that the man was healed, but through faith in the name of Jesus. And not only that, Peter explains that this Jesus whom they had handed over and denied before Pilate was, in fact, “the Author of life,” whom God raised from the dead (Acts 3:15, BSB). That phrase alone—“the Author of life”—reveals that Peter now grasped the eternal nature of Christ. The man he once confessed as Messiah (yet misunderstood in so many ways) he now proclaims as the eternal Son of God, the source of all life.
Then Peter turns their attention to the prophets, declaring that everything that had happened—Christ’s suffering, His rejection, His resurrection—was foretold. “In this way God fulfilled what He had foretold through all the prophets, saying that His Christ would suffer” (Acts 3:18, BSB). He speaks as one who has begun to truly see the unity of Scripture. It is not just that Christ fulfills prophecy in a general sense, but that the entire sweep of redemptive history points to Him.
And so Peter calls the people to repentance: “Repent, then, and turn back, so that your sins may be wiped away, that times of refreshing may come from the presence of the Lord” (Acts 3:19, BSB). Here is a man who has known his own denial of Christ, who has experienced both the bitter grief of sin and the gracious restoration of the Savior. And now, filled with the Spirit, he calls others into that same grace.
There is something quietly astonishing about the transformation of Peter. He who once rebuked Jesus for speaking of His death now proclaims that very death as the centerpiece of God’s plan. He who fled in fear now stands firm before the crowds. What made the difference? The coming of the Holy Spirit. At Pentecost, the Spirit of God brought not just power, but understanding. The Spirit opened the Scriptures to them, and with it, opened their eyes to the majesty of Christ.
I wonder how this passage speaks to you. Have you, like the apostles, walked with Jesus yet struggled to see His glory clearly? Are there places where your understanding of Him still feels partial or dim? The Spirit who opened Peter’s mouth and heart is the same Spirit given to every believer. He delights to reveal Christ to us—not as a distant figure in history, but as the risen Lord who stands at the center of all Scripture and the very center of our lives.
Let us not move too quickly past Peter’s call: “Repent…that times of refreshing may come.” Refreshing! How often our souls grow dry when we forget the living Christ. But He is still the Author of life, still mighty to save, and still calling us to return and be renewed in His presence.
For further reflection, consider these complementary passages: Luke 24:44–49, where the risen Jesus opens the minds of His disciples to understand the Scriptures; and John 14:26, where He promises the Spirit will teach and remind them of all He has said.
