But when that era came to an end and the time of fulfillment had come, God sent his Son, born under the written law. Yet all of this was so that he would redeem and set free all those held hostage to the written law so that we would receive our freedom and a full legal adoption as his children.
What marvelous love the Father has extended to us! Just look at it-we're called children of God! That's who we really are. But that's also why the world doesn't recognize us or take us seriously, because it has no idea who he is or what he's up to.
The Spirit Himself testifies together with our spirit that we are God's children, and if children, also heirs-heirs of God and co-heirs with Christ-seeing that we suffer with Him so that we may also be glorified with Him.
