In Acts 19:1–10, Luke records an important moment in the expansion of Christ's kingdom as disciples in Ephesus receive the promised Holy Spirit. Through this event, we are reminded that one of God's greatest blessings to His people is the gift of His own Spirit dwelling within them. For it is the Spirit who applies Christ's saving work to our hearts, unites us to Christ, equips us for service, and empowers us to live for God's glory.
