In Acts 2 we find this description:
"So those who received his word were baptized, and there were added that day about three thousand souls. And they devoted themselves to the apostles’ teaching and the fellowship, to the breaking of bread and the prayers. And awe came upon every soul, and many wonders and signs were being done through the apostles. And all who believed were together and had all things in common. And they were selling their possessions and belongings and distributing the proceeds to all, as any had need. And day by day, attending the temple together and breaking bread in their homes, they received their food with glad and generous hearts, praising God and having favor with all the people. And the Lord added to their number day by day those who were being saved" (Acts 2:41-47, ESV).
Those early disciples displayed a radical, daring, sacrificial, undiluted devotion in three key areas:
• Devoted to the Savior
• Devoted to the Fellowship
• Devoted to the Mission
Think what a local church would look like if its people were radically devoted to Christ, irrevocably committed to each other, and relentlessly dedicated to reaching those outside God’s family with the gospel of Christ. That is what we mean by an "Acts 2 Church."
