Do We Really Know the Gospel?

Each year, as I teach the doctrine of salvation, I give a quiz to test my students’ understanding of the Gospel. I ask them to imagine that they are in a hospital room, calling on an unbeliever who is at death’s door. The students have time for only twenty-five words to communicate the Gospel. After the 25th word, the patient has passed away. What would the students say in this situation? Are they able to express the Gospel so concisely that if the mortally ill person responds properly, he is saved?
