When they heard "this"

Great time this morning with staff and interns on a mark of a healthy church as found in Acts 2: spirit-empowered gospel preaching. "When the people heard this, they were cut to the heart and said to Peter and the other apostles, “Brothers, what shall we do?”Acts 2:37. What does "this" refer to? Peter's spirit-empowered gospel message. The message cut through to the heart. What else can do this!!!

On the same day, I see this video on the power of God's Word. You've got to see THIS!
