A doctor entered the hospital in a hurry after being called in for an urgent       .He answered the call as soon as possible, changed his clothes and went directly to the operation block.He found the boy's father       in the hall waiting for the doctor. On seeing him, the dad        , "Why did you take all this       to come? Don't you know that my son s life is in danger? Don't you have any sense of      ?"
The doctor smiled and said, "I am sorry, I wasn't in the hospital and I        as fast as I could after receiving the call...And now, I wish you'd calm down work."      I can do my work.”
“Calm down? What if your son is in this room right now, would you calm down? If your own son is      now what will you do?” said the father       .
The doctor smiled again and replied," I will say what Job said in the Bible 'From dust we came and to dust we return, blessed by the name of God'.     cannot extend lives. Go and       for your son.we will do our best by God's grace."
"Giving advice when we re not       is so easy." murmured the father.The operation took some hours       which the doctor went out happily.
"Thank goodness!  Your son is saved ! " And without waiting for the father's reply he carried on his       running. “If you have any question, ask the nurse!"
"Why is he so       ? He couldn't wait some minutes so that I could ask about my son's       ?" commented the father when seeing the nurse minutes after the doctor left. The nurse answered,        coming down her face, "His son died yesterday in a road accident.He was in the funeral when we called him for your son's operation.      now that he saved your son's life, he left running to finish his son's funeral."
Never     anyone...because you never know how their life is and what they're      .
