I think about the dad who had something to give his young son and asked him to hold out his hand. "Why?" asked the little boy with his hands firmly clasped behind his back. The father repeated his request, but the son kept asking "why"—and missed out on the treat his dad wanted to give him.
The Bible says in James 1:17 (NIV) "Every good and perfect gift is from...the Father." But we sometimes worry that He might ask something of us that we are not going to like.
