I wrote this when we received the results of the genetic testing performed on the tissue they obtained from our lost pregnancy. There's nothing I could add to this now, so I'll simply repost what I wrote in January 2015.
As I understand it, "grace" is a gift from God which allows us to do and experience and understand things we couldn't do, experience, or understand on our own. Our lives without grace may lack direction or leave us unfulfilled - my guess is because we don't understand what God wants of us. When we know which way to turn next, it is because of grace. We tend to think of grace as a happy, soothing feeling, but I'm not sure that's always the case. I think sometimes grace hitches a ride with more painful experiences. The kind after which we reflect and say "if not for that, I might never have gotten to this". I think it is in feeling the glow that embraces us when we are with "this" that we can appreciate the grace we've been given.
So in a nutshell, I think grace is a gift from God - received many times over, mind you - which gives us peace and direction and helps guide us toward the things we should be doing and experiencing in our lives. When the chromosomal test results on my miscarried baby came back telling us it was a girl, it just seems right that we decided to name our daughter Grace.
Ephesians 2:8 sums it up quite nicely for me: For by grace you were saved through faith, and this is not from you; it is the gift of God. Our littlest gift sent us on the path toward adoption now, already knowing that whoever the child is we bring into our family at this time, it will be because of Grace.
