Acts 13:16 Then Paul stood up, and motioning with his hand said, “Men of Israel, and you who fear God, listen:
God wants us to tell other people what we know. He does not ask us to teach people every single details about Him or even Israel’s history, just what we know.
Paul had a good understanding about the history of the people, about the scriptures, the prophets and kings and now about Jesus and the fulfilment of all of those stories.
So that is what he recounts here, in simple terms to allow the people around him to understand Jesus.
Share what you know to allow people to understand a bit more about what they are seeking for.
