Gone are the days when men walked into church and shook under the convicting power of God's presence. Instead, our dull, dry-eyed preaching tends to comfort the sinner and condone his sin. We need a return to the original New Testament type of praying and preaching. The early Church moved heaven and earth by their prayers; they changed hearts by their preaching. Peter's message on the day of Pentecost pierced his listeners to the heart. This word "pierced" is the same used when the soldier drove his spear into the side of Jesus, on the cross. Following the day of Pentecost, the disciples prayed for confidence and the place where they were gathered was shaken. They were filled with the Holy Spirit and spoke the Word of God boldly.
