Well, then go hand out Bibles, and your work here will be done. Anything else you could do would distract from the message.
That is basically correct.
The problem is, not ALL of the Bible is the Gospel of the Grace of God.
When Philip was with the Ethiopian Eunuch, there was no method but exposing the eunuch to the Scriptures in (what we know since chapter and verse markings to be) Isaiah ch. 53. Philip preached unto him Jesus from that text.
No method, like, "Do this," nor "Do that," nor "Practice this," nor "Practice that," nor "Pray this," nor "Pray that" . . . . simply believe the report (Is. 53:1) with all your heart.
