The evangelistic power of worship

[Pastor.com] 17 Jul 2006--When unbelievers watch genuine worship, it becomes a powerful witness. On the day of Pentecost, God’s presence was so evident in the disciples' worship service that it attracted the attention of unbelievers throughout the entire city! Acts 2:6 says, “... a crowd came together.”

Why were those 3,000 people converted? Because they felt God’s presence and they understood the message. I believe both of these elements are essential for worship to be a witness.
