Read about God's heart for orphans at Family Life's Hope for Orphans. Here's the last paragraph of the short article:
"Caring for the fatherless is not simply a compassionate and kind act, and adoption is not merely an additional means of growing our families to the desired size. Caring for the fatherless and adoption are at the very heart of God. Caring for orphans is about obedience … it is about knowing the God whom we serve."
