Lev 26 God desires that His people to be light among the nations. He desires that we obey Him and receive blessings but just like an errant child who has been warned, God will bring about cursings to correct His children. “Be sure your sins will find you out.” [Num 32:23] This is as true today as it was then: “Folly is bound up in the heart of a child, but the rod of discipline will drive it far from him.” [Prov 22:15] Like the Israelites of old, today we too face fallow land and fallow hearts.
We foolishly say this was OT; not for us who live under grace and in the NT. A principle is a principle, and God is God. He is “does not go back on his word or change his mind, for he is not a human being who changes his mind.” [1Sam 15:29] God desires that we obey Him now and forever so that He may bless us. “If we confess our sins, he is faithful and just to forgive us [our] sins, and to cleanse us from all unrighteousness.” [1Jn 1:9] Then He will return and heal our land and our people.
