The moral imperative to behave as if we believed in God

 Is there a moral imperative to behave as if we believed in God by obeying His laws after we learn the wisdom of His laws?

The most intellectually respectable position is that of agnosticism. To not waste time is to be more intellectually respectable than wasting time discussing something no one alive will ever be able to prove: whether the Abrahamic God exists and whether there is an afterlife. The moral imperative remains to discuss whether we ought to obey what are said to be the laws of God and if not, why not.

There are only two divine revelations believed to be from the Abrahamic God: the Torah for Jews and the Koran for gentiles. The latter does not contain 36 capital offences and is intended for all humanity.
