What a wonderful way to explain it.
A sick man turned to his doctor, as he was preparing to leave the examination room and said,
"Doctor, I am afraid to die. Tell me what lies on the other side."
Very quietly, the doctor said, "I don't know."
"You don't know? You, a Christian man, do not know what is on the other side?"
The doctor was holding the handle of the door; from the other side came a sound of scratching and whining, and as he opened the door, a dog sprang into the room and leaped on him with an eager show of gladness.
Turning to the patient, the doctor said, "Did you see my dog's behavior? He's never been in this room before. He didn't know what was inside. He knew nothing except that his master was here, and when the door opened, he sprang in without fear. I know little of what is on the other side of death, but I know my Master is there and that is enough."
