"So it shall be when all of these things have come upon you, the blessing and the curse which I have set before you, and you call them to mind in all nations where the LORD your God has banished you, and you return to the LORD your God and obey Him with all your heart and soul according to all that I command you today, you and your sons, then the LORD your GOD WILL RESTORE YOU from captivity, and have compassion on you, and will GATHER YOU again from all the peoples where the LORD your God has scattered you. If your outcasts are at the ends of the earth, from there the LORD your God will gather you, and from there He will BRING YOU BACK. The LORD your God will BRING YOU BACK INTO THE LAND which your fathers possessed, and you shall possess it; and He will prosper you and multiply you more than your fathers. Moreover the LORD your GOD WILL CIRCUMCISE YOUR HEART and the HEART OF YOUR DESCENDANTS, to love the LORD your God with all your heart and with all your soul, so that you may live."
Israel has experienced every curse of Moses. They have been oppressed inside the land (during Judges), they have been removed to another nation (Assyria and Babylon), and finally they have been scattered throughout all nations (by Rome). All three steps of the curse have literally been fulfilled exactly as Moses wrote it.
Now there is a future that must happen exactly as Moses wrote it. All Israel must be restored to the land, not like they are now, but prospered and multiplied far beyond even Solomon's glory. Then a greater thing will happen. God will spiritually save the nation. He will circumcise their hearts. He will save them in such a way that even their children and children's children will obey God. This has never happened. This is the grace of God!
Don't diminish the grace of God. Maybe God saved you from a terrible life of sin. That is your measure of the grace of God. You drank too much. Now you don't. You were on drugs. Now you aren't. You were a murderer. Now you aren't. You were a bad husband or wife. Now you aren't. What God has shown you is like one raindrop compared to a worldwide flood. When God saved you, He saved one sinner and made you His son. When God saves Israel, He will save an entire nation and all their future generations, and He will make the entire nation His son.
How does that magnify the grace of God?!
For me to live is Christ.
