I read this article recently and thought you might enjoy it too.
THE SOVEREIGNTY OF GOD IN FOSTER CARE
Here’s a snippet:
Yet, for all that we may be able to provide, God’s ability to be good to her in a difficult environment is far greater than any good we could offer her in a comfortable one. No amount of “good” we can give her can compare with the goodness of the sovereignty of God in her life, wherever she may end up living it. There are no guarantees in foster care, except one – God is sovereign in the life of this baby girl. He is good, and He will be good to her always, no matter where she lays her head at night.
