题目内容：

    A little boy was playing in his sandbox on a Saturday morning. 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 pushed and pulled, but every time he thought he had made some progress, the tone tipped(倾斜) and then fell back into the sandbox. The little boy tried his best, but his only reward(奖赏) was to have the stone fall back.

Finally the boy cried. All that time the boy's father watched him from his living room window. At the moment 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 that you had?" The boy said sadly, "But I did, daddy, I did! I used all the strength that I had!" "No, son, you didn't ask me." With that, the father reached down, picked up the stone and removed it into sandbox.

Do you have stones in your life that need to be removed? Are you discovering that you are too weak 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 on our own?
