A little boy was spending his Saturday morning playing in his sandbox（沙坑）.While he was building roads and houses in the soft sand,he discovered a large stone in the middle of the sandbox.
The little boy tried to move it,but every time he thought he had made some progress,the stone fell back into the sandbox.The little boy tried his best,but his only reward（回报） was to have the stone fall back,hitting his fingers.
Finally,the boy cried.All that time the boy\’s father watched him from his living room window.The moment the boy\’s tears fell,his father came to the boy and the sandbox.Gently but surely he said,"Son,why didn\’t you use all the strength（力量） that you had?"Sadly,the boy cried back,"But I did,Daddy,I did!I use all the strength that I had!" "No,son,"said the father."You didn\’t use all the strength you had.You didn\’t ask me."Then the father moved the stone from the sandbox.
Do you have "stones"in your life that need to be moved?Are you discovering that you aren\’t strong enough to lift them?There is ONE who is always ready to give us the strength we need.Isn\’t it funny how we try so hard to do things ourselves?
