So then, brothers, we are debtors, not to the flesh, to live according to the flesh. For if you live according to the flesh you will die, but if by the Spirit you put to death the deeds of the body, you will live. For all who are led by the Spirit of God are sons of God. For you did not receive the spirit of slavery to fall back into fear, but you have received the Spirit of adoption as sons, by whom we cry, Abba! Father! The Spirit himself bears witness with our spirit that we are children of God, and if children, then heirs--heirs of God and fellow heirs with Christ, provided we suffer with him in order that we may also be glorified with him. (ESV)
Here Paul wraps up our salvation by saying we are God's adopted children with all the rights and responsibilities that go along with this.
As I think about adoption there are three points I want to highlight. First, there are costs associated with adoption. In our case, the mothers of our kids had to give them up, I am sure this was not an easy thing to do. For one we know the reason was the the mother wanted a better life for her child. In God's case, He had to send His Son to earth to pay the penalty for our sins. The cost, Jesus died on the cross. The second point is that we have a new identity as a result of adoption. The birth parents of our kids lost all rights, responsibilities and obligation to their kids when they signed the adoption papers. Conversely, my wife and I took on these same rights and obligations. In the same way since we are now God's children we are heir with Christ. We need to live our life in such a way as to reflect this. Neil T. Anderson in his book Victory over the Darkness does a great job of spelling out who we are in Christ. The last point I want to make is that adoption leads to a greater sense of intimacy. My son shared at an open mic about how happy he was that we came and got him and made him part of our family. Needless to say there as not a dry eye in the church after that. But it got me thinking, when was the last time I really thanked God for sending His Son to die for me? Next time you take communion think about that.
So what does it mean to you to be a child of God? Should you be living your life any differently if you took to heart the idea that you are an heir with Christ?
