Embroidering(刺绣)
When I was a little boy living in New York, my mother used to embroider a great deal. I would sit at her knee and look up from the    36    and ask what she was doing. She   3 me that she was embroidering. I told her that it looked like a mess from where I was. As from the underside I watched her work within the    38  of the little round hoop(铁环)that she held in her hand, I complained to her that it sure looked   39   from where I sat.
She would smile at me, look down and  40   say, "My son, you go about your    41   for a while, and when I am finished with my embroidering, I will put you on my    42   and let you see it from my side."
I would wonder why she was using some dark threads along with the    43   ones and why they seemed so jumbled(混乱的)from my   44  . A few minutes would pass and then I would hear Mother's voice say, " Son, come and sit on my knee." This I did only to be  surprised and    45  to see a beautiful flower or a sunset. I could not    4 it, because from underneath it looked so messy.
Then mother would    47   to me, "My son, from underneath it did look messy and jumbled, but you did not realize that there was a   4 plan on the top. It was a    49   . I was only following it. Now look at it from my side    50   you will see what I was doing."
Many    51    through the years, I have    52   up to my Heavenly Father and said, “ Father, what are You doing? ” He    53   , “ I am embroidering your    54  . ”I say, " But it looks like a mess to me. It seems so jumbled. The threads seem so dark. Why can't they all be bright ? " The Father seems to tell me, " My child, you go about your business of doing My business, and one day I will bring you to    55   and put you on my knee and you will see the plan from My side. "
