[Billy Graham ... et al].

"The call for decision-the invitation-is therefore not something just added to the end of an evangelistic sermon as an afterthought. Instead, the whole sermon leads toward it.... It is not only valid to issue an invitation, it is essential. The invitation may take many forms, but if people hear our message and go away without having been confronted with the clear-cut call, "What do you think about the Christ?" (Matthew 22:42), then we have failed in our proclamation of the gospel."
