Adversity can make us strong.

A man found the cocoon of a butterfly. One day a small opening appeared. He sat and watched the butterfly for several hours as it struggled to force its body through that little hole.  Then it seemed to stop making any progress. It appeared as if it had got as far as it could, and it could go no further.  

The man decided to help the butterfly. He took a pair of scissors and snipped off the remaining bit of the cocoon.  The butterfly then emerged easily. But it had a swollen body and small, shrivelled wings.  The man continued to watch the butterfly because he expected that, at any moment, the wings would enlarge and expand to be able to support the body, which would contract in time.  Neither happened! In fact, the butterfly spent the rest of its short life crawling around with a swollen body and shrivelled wings. It was never able to fly.  

What the man, in his kindness and haste, did not understand was that the restricting cocoon and the struggle required for the butterfly to get through the tiny opening were God's way of forcing fluid from the body of the butterfly into its wings so that it would be ready for flight once it achieved its freedom from the cocoon.  

Sometimes, God will have us struggle in life. That's because He has a plan for us. He knows what's best and He knows what He is doing. We just need to trust Him.
