Holiness has requirements that are summarized in Bechukkotai along with the penalties for disavowing our holiness. To disavow – not keep our vow to YHVH – is to do rebellion. Doing rebellion gets us kicked out of the Land, perhaps permanently if we refuse to repent.
Shmittah and Jubilee years are both prophetic and a matter of our hearts. So far, the House of Jacob has shown the LORD we will NOT let the Land have its rest. Will we continue this attitude into the future?
