Without the birth of Jesus Christ there would be no atonement and no adoption.  When Hope was born you and I gained our freedom…  

The Lord Jesus was born under the law, lived under the law, and died under the penalty of the law which we broke, and in paying our penalty, He delivered us from any claims which the law had against us. He died under law, and in His resurrection, was raised into a realm where law as a legalistic system does not exist.
