“For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.”
King James Version (KJV)
8:2 The law of the Spirit - That is, the gospel. Hath freed me from the law of sin and death - That is, the Mosaic dispensation.
Ro 8:2 For the law of the Spirit of life. The Spirit of life must be the Holy Spirit. The whole phrase is equivalent to the Gospel, which has been given to men by the agency of the Holy Spirit. The Spirit has quickened us into a new life, and as we have died to the law and to sin, we are freed from them. Wesley says that the meaning is the "Gospel has freed us from the Mosaic law". That the law of the Spirit of life describes the Gospel is shown by Ro 8:3, which explains this verse.
