Religion that God our Father accepts as pure and faultless is this: to look after orphans and widows in their distress and to keep oneself from being polluted by the world. (NIV)
That verse is lived out in lives of Christians in different ways. Some of us are called to adopt, but not all of us are. There are many ways to look after orphans besides adopting. Prayer is a huge way you can help people you know who are adopting - pray for the health of their future children, pray for the potential adoptive parents as they prepare to parent a child from different circumstances, pray for the adoption process and the social workers involved. Go visit this family at Filled with Praise for another way you can help "look after orphans." They have Christmas ornaments for sale.
