Pentecost Sunday is a day to celebrate hope, a hope evoked by the knowledge that God through His Holy Spirit is mightily at work among His people. It is a celebration of newness, of recreation, of renewal of purpose and of transformation. It is a celebration of God's ongoing work among all the nations in the world. But most of all, it is a recognition that God's work is being done through His people - as He pours out His Spirit upon them (Joel 2:28). This focus on the church's mission to the world, and the enabling presence of God through the work of the Holy Spirit in the church (to empower that mission) should provide a powerful impetus for churches today, especially those like Cornerstone. Pentecost gives us a tremendous opportunity to use this time to see people transformed through the work of the Holy Spirit in their lives.
