Does God still warn us against the same things He warned Israel about?

Les explains that although we are not under law but under grace, the God of the Old Testament, the God of the Mosaic law, is the same God we deal with today, and He has not changed. The things God hated back in Genesis, He hates today. What He admonished Israel not to do for their own good, He admonishes us today not to do for our own good, because He hasn't changed. This is just as applicable today as it was for Corinth in Paul's day and as when it happened in Exodus. The circumstances of the world have not changed, and the things that damaged health in Israel's early days are no different today.
