Think about the ramifications of that for a bit. If, as she implies, humans are in some way kin to God, then God being our kinsman redeemer (גואל gw'l) takes on a whole new meaning, doesn't it. And murder is no longer just killing someone. It is, in some sense, an attack on God's family—whether the person is a Christian or not!
Lots to think about here...and this is only on page 3!
