Acts 28
"And he was explaining to them by solemnly testifying about the kingdom of God and trying to persuade them concerning Jesus, from both the Law and the Prophets, from morning until evening" (v23). In Rome, Paul invited the Jewish leaders to come and listen to him talk about Jesus. His presentation was quite different from his encounters on Malta, where many were dramatically healed by the Spirit.
Paul's logical explanations and miraculous healings were both true to the Person of Jesus. We can't afford to choose "a method" of evangelism; in all ways and places, we are witnesses of Jesus Christ.
