Under Grace?

Usually this is where I add something that the Lord taught me while reading through the Bible, but today, my time in Leviticus 26 left me with more questions than anything else. Read Leviticus 26 for yourself, and answer these question, if you would. . .

Is it different for us because we live "under grace" and they didn't?

(That is of course outside of the obvious that these statements are for Israel and not for us today.)

How is it different?

I know, in my head, the difference between being under the law and under grace, but what does it look like when it comes to our actions?
