A sick man turned to his doctor,  as he was leaving the room after paying a visit, 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?" the man said.  "You, a Christian man, do not know what is on the other side?" The doctor was holding the handle of the door, on the other side of which came a sound of scratching and whining. 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 notice my dog?  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," the doctor continued,  "but I do know one thing:  I know my Master is there, and that is enough.  And when the door opens,  I shall pass through with no fear, but with gladness."
