These are the words that the Lord gave to the people of Israel, promises that were fulfilled by God, so much so that He said that He would take them out with strong hands from the yoke in which they were under the command of Pharaoh and they were released.
When God speaks, we have to obey and believe that it was He who spoke, just as when He promises, because He fulfills because our God is powerful and does not fail His promises.
In chapter 36 of the book of Ezekiel we can see that God is speaking about the promises of the people of Israel and all the things that He would do with them:
27 And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them.
28 And ye shall dwell in the land that I gave to your fathers; and ye shall be my people, and I will be your God.
29 I will also save you from all your uncleannesses: and I will call for the corn, and will increase it, and lay no famine upon you.
Here in these verses from 27 to 29, we can see the promising words that God was saying in favor of the people, telling them that they would inhabitate the land that their parents inhabited and the Spirit of God would be in each of them.
We can also observe that God told them that they would walk under His statutes, and they would be God’s people, and He would be their God. The Lord told these people that He would keep them from all filth and fill their barns so they would not starve.
How great is the mercy of God, seeing these promises fulfilled by God Himself.
