I've also been blessed with family of choice that expands the blessings in my life: sisters of choice, grand-children of choice and a particularly spiffy foster daughter. Over the years as life and circumstances change, the connections continue to bless and inform my life in such amazing ways. If we haven't spoken in a while, but you need me to meet your step-niece at the airport and drive her a couple of hours to your sister's house, I'll be there with joy and gratitude that love is the tie that binds.
But in the end, anyone we love can come up short. Maybe occasionally. Maybe often. In the most serious cases we may even need to love from afar or with significant boundaries established. And all of that makes loving seem so dangerous at times that we limit it, circumscribe it, hide from it in an effort to not be hurt.
This may be why my most favorite attribute of God is described in this verse from 1st John:
* 1 John 4:8
