Pentecost and the Church’s Witness

Acts 2:36-41


Pentecost does more than mark a moment in the church calendar—it reminds us that God is still drawing near to his people with power, mercy, and love. Pentecost creates a confessing church, and a confessing church becomes a witnessing church. Before we can bear witness to the world, we first learn, again and again, to confess who Jesus is and what his presence means for our lives.

In Acts, Peter boldly proclaims, “God has made him both Lord and Christ, this Jesus whom you crucified.” The people are cut to the heart. That first response of faith is confession: naming who Christ is, and recognizing who we are in light of him. Pentecost reminds us that life is not centered on ourselves—it is centered on Jesus Christ, who calls us, redeems us, and gives purpose to our lives.

The coming of the Holy Spirit also brings what older Christian language calls “quickening.” In the historic phrase “the quick and the dead,” “quick” means the living. To be quickened is to be made alive. As John 6:63 says, “It is the Spirit that gives life.” Through the Spirit, God awakens what was spiritually lifeless in us and renews us from within.

Before the Spirit’s work in us, we are spiritually dead. But in Christ, through the gift of the Spirit, we are brought to life again. John Calvin called this regeneration—a renewal that begins in grace and continues as God forms us into faithful disciples.

The Holy Spirit teaches, guides, and gently shapes us into the people we are meant to be—the witnesses we are called to become. That kind of transformation asks something of us as well: a willingness to slow down, to listen, and to trust. As we confess Christ and remain attentive to his leading, the Spirit equips us to live out our faith with courage, tenderness, and compassion.

I was reminded of this in a very personal way last Sunday morning as I sat down to write Prayers for the People. On my desk was a list of names and circumstances held in prayer—members of our congregation, family in San Antonio, missionaries in La Paz and Uganda, friends in Mexico, and the children and families entrusted to our care. That morning, I felt especially drawn to pray for Avery, Michele, and their little boy. In that moment, I did not fully understand the need, but the Spirit did. Later we learned that Granite Alder had arrived very early—13 weeks ahead of schedule. Our little “Alder Rock” has already inspired so much love and so many prayers, and he will continue to need both in the days ahead. Lord, bless this little boy.

This is how the Holy Spirit moves among us even now—often quietly, often tenderly, but always faithfully. Scripture reminds us that “the Spirit gives life” in John 6:63 , that “all who are led by the Spirit of God are children of God” in Romans 8:14 , and that we “receive power” to be Christ’s witnesses in Acts 1:8 . So as we move through these days together, may we stay open to the Spirit’s leading—ready to pray, ready to love, and ready to bear witness to the grace of Jesus Christ wherever he sends us.

  • The Spirit convicts us and draws us back to Christ.
  • The Spirit equips us with what we need for faithfulness.
  • The Spirit sends us out in love to serve and witness.
  • The Spirit sustains us with hope, comfort, and peace.

Between Two Advents: The 5 W’s of Pentecost and the Life of the Christian

By Pastor Cobb • May 24, 2026
Acts 2: 1 - 4 When the day of Pentecost arrived, they were all together in one place. 2 And suddenly there came from heaven a sound like a mighty rushing wind, and it filled the entire house where they were sitting. 3 And divided tongues as of fire appeared to them and rested [ a ] on each one of them. 4 And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance. The Christian life is lived between two great arrivals. Well actually three; dare I say, the Baby Jesus (The Messiah), the Holy Spirit, and the Return of the King. But what is in the in between? Ok, that’s a lot of pop culture, guess the references and I will take you to lunch. Burgers at The Salt Post! We look back to Pentecost — when the Holy Spirit descended upon the church with wind, fire, and power. Yet we also look forward to the return of Jesus Christ and the fulfillment of God’s Kingdom. Still, we are all pilgrims. And are we making any progress? In this series, we explore how the Holy Spirit forms believers to live faithfully in the tension between these two moments. Through the themes of: Waiting Wanting Watching Wondering Working We will discover how the Spirit sustains faith, deepens grace, and teaches us how to live in a restless world while longing for the Kingdom to come. Pentecost was not the end of the story. It was the beginning of a Spirit-filled people learning how to wait for their King. Join us as we journey through Acts of the Apostles and explore what it means to live between the coming of the Spirit and the coming again of Christ. think of it this way, the Christian life is lived in the hallway between two doors: The door Christ opened at Pentecost, and the door He will open when He returns. In Montesano, we have a long hallway with a door to the laundry room at its end. Do you remember those creepy Alfred Hitchcock movies (or Steven King) where the hallway the person has to get down gets longer and longer. And they run and it stretches and they never get any closer to the end? That what life feels like most the time right? Where is that finish line? Pentecost was never the finish line. It was the beginning of life in expectation. Disciples wait all the time – on a hill, at a well, in a boat, in an upper room. Paul waits in limbo…in a boat, on beach, in a cell, multiple cells. John Waits on an island… The church still waiting today Humanity is always longing for restoration, we wait each day, for change, hope, love, signs, news, hurry up and wait doesn’t just apply to the Soldier. Join us Sunday mornings at 10:00 I look forward to hearing from you. In Christ, Pastor Cobb
