Great article on adopting through foster care.
Gives you some great information and statistics.
You might not be interested in adopting yourself, but as believers we are ALL called to care for orphans and widows. It doesn't mean adoption. I have not adopted. We may not adopt. We have thought about it and might at some point. But, until then, I still need to advocate however I can for orphans.
God commands it. It is not optional or the calling of only some.
I'm tired of hearing people say "I'm not called to that" when confronted with a need. Bull! You are if you are called to salvation by God! You are called to care. You were created to care. And, you are disobedient if you aren't doing something.
That something looks different for different people. Maybe you should sponsor a Bridge of Hope child through Gospel For Asia or sponsor a Compassion child or adopt a child from Angel Tree (or organize an angel tree for your local church) or become a CASA volunteer or become a foster parent or love on the kids in your neighborhood whose parents aren't around and don't seem to care much.
