1. The mission of the twelve disciples was to preach the good news of the Kingdom of God, heal the sick, and cast out demons. They were sent out by Jesus to proclaim his message and demonstrate his power. 2a. The Holy Spirit is understood as the third person of the Trinity, the divine presence and power of God at work in the world and in believers. It is often referred to as the Spirit of God or the Spirit of Christ. 2b. On the day of Pentecost, the Apostles experienced a sudden sound like a mighty rushing wind and tongues as of fire resting on each of them. They were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them, allowing them to be understood by people from various nations. 3. Peter's speech on the Day of Pentecost (Acts 2) explained the miraculous events occurring. He proclaimed that the outpouring of the Holy Spirit was the fulfillment of Joel's prophecy. He then declared that Jesus, whom they had crucified, was the Messiah, resurrected by God and exalted to His right hand. Peter called the crowd to repent and be baptized for the forgiveness of their sins and to receive the gift of the Holy Spirit. 4. The conversion of Saul occurred on the road to Damascus. Saul, a persecutor of Christians, was struck down by a blinding light and heard the voice of Jesus asking, "Saul, Saul, why do you persecute me?" He was blinded for three days and was led to Damascus. There, Ananias, a disciple, was sent by God to lay hands on Saul, restoring his sight and filling him with the Holy Spirit. Saul then immediately began to preach Jesus in the synagogues. 5. In Lydda, Peter encountered a man named Aeneas, who had been paralyzed and bedridden for eight years. Peter said to him, "Aeneas, Jesus Christ heals you. Get up and make your bed." Immediately, Aeneas was healed. This miracle led many of the residents of Lydda and Sharon to turn to the Lord.
