After the dramatic outpouring of the Holy Spirit at Pentecost, Peter’s sermon led to the conversion of 3,000 people (Acts 2:41). But what happened next was just as powerful: the Spirit-filled individuals and formed a community. In verses 42-47, Luke gives a snapshot of this newborn church, a model of what gospel transformation looks like in real life. In a world divided by class, race, gender, and status, we see the Spirit unite by grace.
