[Paul, continuing his address to the council in Athens:] "God overlooked people's ignorance about these things in earlier times, but now he commands everyone everywhere to repent of their sins and turn to him. For he has set a day for judging the world with justice by the man he has appointed, and he proved to everyone who this is by raising him from the dead."
When they heard Paul speak about the resurrection of the dead, some laughed in contempt, but others said, "We want to hear more about this later." That ended Paul's discussion with them, but some joined him and became believers. Among them were Dionysius, a member of the council, a woman named Damaris, and others with them.
— Acts 17:30-34 NLT
Paul knew that his core message of Jesus' death, burial, and resurrection were tough concepts for people to believe in his day — as it is in our day. A crucified Messiah was a crazy idea to both Jews and Gentiles. The idea of someone being raised from the dead was outside most people's human experience. But, these concepts are crucial to the Good News he preached, and people have to believe them to be saved. Paul not only taught that people must believe in these ideas; he also invited them to participate in these events in their response to Jesus.* Yet, for those of us who believe and have shared with Jesus in death, burial, and resurrection, Paul's teaching is not only true; it is life-transforming!
