The answers to why would you adopt a child, when you already have three?

Because we believe that this life is not our own.
Because we believe that in the end, it won't matter what career ladders we climbed or financial investments we made or what gadgets we could afford. It will matter that one life was saved.
Because we have seen hopelessness in Ethiopia and elsewhere, but believe in all hope that each child is a child of God.
Because we believe that the orphaned street child who plays street soccer on the rough pavement of the streets of Addis Ababa is no less valuable to the Creator than the polished child on a suburban soccer team here in America.
Because we see nothing more worthy of our focus, time, resources, and lives.Because injustice is a wrong worth righting.
Because the poor child is still a child.
Because we know that, while adoption is not the solution in and of itself to the orphan crisis 143 million times over, we have seen with our own lives how it rescues the lives of those who can be adopted.
Because we believe that Jesus died for redemption, not just for eternity, but for our lives on this planet and we believe we can be vessels of that redemption for children's lives here.
Because we know that, if it were our own flesh and blood, we would want someone to love them and call them family, too.
Because, really, these kids are no different from your own. Not at all.
Because it's just not okay with us to say no to a child who needs a home when we have one.
Because it's just not okay with us to say no to a child who needs a family when we have one.
Because it's just not okay with us to say no to a child who needs room to thrive when we have room and can make room.
Because it's just not okay with us to do nothing.
Because it won't be okay with them if we do nothing.
Because it's just not going to be okay to do nothing.
"Rescue the perishing; don't hesitate to step in and help. If you say, "Hey, that's none of my business," [i.e. "that's not for me"] will that get you off the hook? Someone is watching you closely, you know— Someone not impressed with weak excuses." -Proverbs 24:12 (The Message)
"Once our eyes are opened we can't pretend we don't know what to do. God, who weighs our hearts and keeps our souls, knows that we know and holds us responsible to act." Proverbs 24:12

Yet again, I did not write this, I copied it off of a blog that I had read. When I read this blog it spoke directly to my thought process. I have told so many people that having my children, and knowing that we are so blessed is what has really made the urge to adopt a child grow in me. How can I look at my healthy, well-fed, clothed , comfortably living with beds and pillows, and loved ever so much children and not think of all of the orphaned children in this world. It breaks my heart to know that there are children the same age as Max, Emma and Samuel, out there in this big huge world, without a mom or dad to call their own.
Pray for God to watch over our orphaned daughter while we try our hardest to make our way to her!
