Faith sees sin and death put to death with Jesus, and so then we also put sin and death to death in us. But in Jesus, it is not ‘just’ sin and death which is put to death, but also THE LAW OF SIN AND DEATH, and it is this law that He has dealt with and removed for us.
The automatic law that sin=death no longer holds true, because it is now sin=the death that Jesus took for us. Since the death has been removed from the equation, the sin now has no leverage to bear against us. If sin and its death have been forgiven, then they no longer have any authority in life.
Because of His forgiveness in the form of the cross, the law of sin and death is disabled, no longer holds true. Sin and death are as if they never had been, they have no outward consequence, because they are not in the creational plan of God. Only life has a place in God’s [new] creation, and this life is freely available without further ado, because for us to have His life in us is what His plan is and always has been.
The Mosaic law or any “law” that denies the absolute power of God to forgive sin AS HAS ALREADY BEEN EXPRESSED ON THE CROSS are the same laws that become to us the laws of sin and death, before we appreciate the very nature of the love of God as expressed in the sacrifice for sin that Jesus made, when He gave His all, His whole being, to convey to us the understanding that God DOES NOT HOLD SIN AGAINST US.
Refusal to believe this means you are believing in a lesser god than that who the Father of Jesus actually is, and the consequences of refusing to believe this truth will mean you will be stuck in some contrived conditional legalistic redemptive process which actually has no power to redeem.
