Watch myself very carefully, don't become corrupt

Deuteronomy 4:9-31
The Load showed at Horeb, Israelite could not see any image of the Load, but the voice, therefore watch yourself, so that you  do not become corrupt and make an idol for yourselves, an image of any shape.
The Load is a consuming fire, a jealous God.
After you have lived in the land a long time, if you then become corrupt and make any kind of idols, doing evil in the eyes of the Load and provoke him to anger, you will quickly perish from the land that you are crossing the Jordan to possess. The Load will scatter you among the peoples, and only a few of you will survive among the nations. But if from there you seek the Load your God, you will find him if you look for him with all your heart and with all your soul.
For the Load is a merciful God; he will not abandon or destroy you or forget the covenant with your forefathers.
Why?
Warning Israelite before they crossed the Jordan river to get the good land. Do not make any idols for them selves. It will make them quick perish and be scattered to many nations and become only a few.
Even though, if you look for the Load you will find him if you look for him with all your heart and with all your soul.
Warning them, but still has a hope, the Load is waiting for their return. The Load is a jealous God, but he is a merciful God also.
How?
Follow his command and obey his decrees is the best choice for all of us. When I am pride then I will forget the Load, so watch myself, the heart.
