Excerpt from the introduction
We see in Peter the change he underwent from having a narrow, parochial perspective to having a great vision for the world. The turning point was in Joppa, where Peter received the vision that Gentiles did not have to become Jews first. This threw open wide the doors of the church. This teaches us that, in the Bible, visions are not for one’s comfort; rather, they challenge a person to do something risky.
Paul’s experience on the Damascus road was likewise life changing. He was determined to focus on Christ, not the law. The early church caused an explosion that sent sparks in all directions. Paul was the touchstone of much debate becasue he took theology so seriousely. Unity was important to him, but not at the cost of truth. That principle must always guide the church.
