The law is like giving rules to children. Obviously when they grow up, this will change. The change that occurred was through education and enlightenment, adults should operate to something other than laws.
Laws for children have to be comprehensive because they lack the understanding that lies behind those laws. Adults simply need to see what the driving Spirit behind the law is.
Getting to know the law giver on a personal level is to render the laws obsolete, because now you know the law giver and are familiar with His driving force, His Spirit and character.
Any attempt by law keepers to try and continue the law into the realm of the Spirit is ridiculous, it is like trying to convert Christians to Judaism.
And using names like Jehovah etc, for our God, totally disregards the use of the word Father for Him, as was used by Jesus, and Paul even dares to say “daddy”.
