Peter goes from being scared, full of fear and hiding away from authorities to being a bold public speaker within a matter of days. Peter is transformed. But why? And what can we learn from Peter's Pentecost Sermon - his first public speech - in Acts 2? This week we look at Acts 2:14-41 as we carry on our ORIGIN series (Book of Acts sermon series), looking at the birth of the church and asking why this Man, Jesus, from 2000 years ago still has a major impact on the world today.
