You meant 613. There is not really 613 laws. That is rabbinical.
Baptism (mikveh) is a Temple law. Do you follow that?
You need to know the "to who, when, how to, and where" of these commandments.
Perhaps if I ask a question it might help?
If you do not have parents, should you keep the obeying parents commandment?
If the criteria for a commandments does not present itself, does that mean the commandment is abolished? Of course not.
Our High Priest has all of this under control in the Heavenlies, in a higher order, where such criteria still exists and He offers intercession daily.
