It was written by Moses, "the finger of God" being a metaphor for the Divine inspiration of God. Are you really that childish in your thinking? "In his own hand" ? Damn. You must have been around 8 years old when you died.
Its not about being greater then the law. Once a person masters the law, the light, by understanding the words and subjects, and does it, they are no longer subject to judgement for sin. They have passed from death to eternal life. Jesus fulfilled the law, complied with its demands, and receive the promised reward of the righteous.
As Jesus said to all of you earthlings, "For as long as heaven and earth endure the Law of God will remain in effect and in full force." as can be witnessed by anyone with a nose that can smell your abject state of corruption.
