Why did Christ's crucifixion make us dead to the law?
Christ's crucifixion makes believers dead to the law because we were crucified in the person of old Adam on the cross, delivering us from the law's hold. This allows us to be married to another—Christ raised from the dead—so we serve in newness of spirit, not the oldness of the letter, and bring forth fruit.
Les teaches that we are delivered from the law, being dead wherein we were held—crucified in the person of old Adam on the cross—so we should serve in newness of spirit and not in the oldness of the letter. The letter is the law, the Ten Commandments. By the body of Christ, that is, His crucifixion, we become dead to the law so we can be married to another, even Him who is raised from the dead, and bring forth fruit. The Holy Spirit indwells us and becomes our law, so we are not lawless but have something far better.
