I need to go on another rant here.
I'm in the process of adopting a child internationally. That process has me taking parenting training with a bunch of other people adopting internationally, most of whom were led to do so by God. I have thought A LOT about the safety of adopting internationally, and the impact on my exiting family. In deciding which country to choose to adopt from I considered things like whether I'm required to go to that country twice, how likely I am to return in one piece, whether or not the child I'd be adopting was stolen from their parents and sold to me, exactly what am I supporting by paying an orphanage, etc. (When I say "I" in this case, I actually mostly mean my wife)
Many of the people I've been in training with have explained that God guided them to adopt from a particular country, or a particular child. They're explaining how they're making multiple trips to some war riddled nation in Africa because it was God's plan. They have faith that God will return them home intact. That's a biiiiiig risk. Some of those nations are not exactly safe places to travel. Some of them require that you pay the orphanage in cash. How safe do you think it is to travel through some African warloard's land with a bag of $5,000 in cash? Twice. Are you getting a child that was stolen from their parents to be sold to you? Are you getting a child that was conceived for the purpose of making money off of you? Are you risking your existing children's happiness and stability by making this choice to risk your life (most of them have kids already)?
Faith can lead people to make ill-informed decisions. If it takes the place of rational thought (which it must), it comes at a real cost.
