The law of sin and death is the devil's law. The law of the spirit of life in Christ Jesus is God's law. Romans 8:2 says, "For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death."
We have the promise that when Jesus comes again, this last enemy shall be put underfoot. Christ came to destroy "him that had the power of death." Satan isn't destroyed yet, but he will be put in the bottomless pit for a thousand years after Jesus returns. After the end of all things, Satan will be put in the lake of fire and brimstone (Rev. 20:10).
