Theophilus, I wrote about Jesus in my earlier book. I wrote about all he did and taught
until the day he was taken up to heaven. Before Jesus left, he gave orders to the apostles he had chosen. He did this through the Holy Spirit.
After his suffering and death, he appeared to them. In many ways he proved that he was alive. He appeared to them over a period of 40 days. During that time he spoke about God's kingdom.
