"Moody and Sanky, working shortly before 1900, could come right to the subject of salvation because they were talking to people who at least had a memory of Christian content. Therefore they didn't need to lay a groundwork of a personal God and a God with character. They could use the word "God" and everyone knew they meant the Judeo-Christian God.
But we often function as if the consensus around us is still the same as it was in Moody's day, and that is a mistake. With people today I practically never start with how to be saved, I start with a God who is there. If God is not there then salvation is just another trick, just another way to get high, like grass."Still true today!
