Deuteronomy 9

"After the LORD your God has driven them out for you, do not say to yourselves that he brought you in to possess this land because you deserved it. No, the LORD is going to drive these people out for you because they are wicked. It is not because you are good and do what is right that the LORD is letting you take their land. He will drive them out because they are wicked and because he intends to keep the promise that he made to your ancestors, Abraham, Isaac, and Jacob. You can be sure that the LORD is not giving you this fertile land because you deserve it. No, you are a stubborn people. "Never forget how you made the LORD your God angry in the desert. From the day that you left Egypt until the day you arrived here, you have rebelled against him.
Deu 9:4-7

Since when did I receive something form God that I truly I deserved?

I remember a pastor (or is it a teacher) defining grace as getting something that you do not deserve.

Listening to pastors and preachers preach about law versus grace, I, in my mind developed this understanding that the law is a device for the salvation of the Israelites. It’s like a state law where if one got convicted of a crime, punished for it and after serving that punishment he/she is cleared of the crime. Maybe it is, maybe it is not. The relationship of God with the Israelites shows more of his grace. How many times have the Israelites angered God and how many times have God forgiven them?

The law reveals sin but, I think, the most important thing that the law has done and is doing is to reveal grace. Getting something you do not deserve like mercy, salvation, blessings and even trials.

And I prayed, 'Sovereign LORD, don't destroy your own people, the people you rescued and brought out of Egypt by your great strength and power. Remember your servants, Abraham, Isaac, and Jacob, and do not pay any attention to the stubbornness, wickedness, and sin of this people. Otherwise, the Egyptians will say that you were unable to take your people into the land that you had promised them. They will say that you took your people out into the desert to kill them, because you hated them.
After all, these are the people whom you chose to be your own and whom you brought out of Egypt by your great power and might.'

Deut. 9:26-29
