As I found the waiting very frustrating today, a fellow adoptive Mom offered the following verse as encouragement. 

But these things I plan won't happen right away. Slowly, steadily, surely, the time approaches when the vision will be fulfilled. If it seems slow, wait patiently, for it will surely take place. It will not be delayed.

Habakkuk 2:3 (NLT)

I hope you find this verse encouraging as well.  I now have it posted in my cubicle at work.  God is in control.
