Deuteronomy 6:10-12, 18
Then it shall come about when the Lord your God brings you into the land which He swore to your fathers, Abraham, Isaac and Jacob, to give you great and splendid cities which you did not build, and houses full of all good things which you did not fill, and hewn cisterns which you did not dig, vineyards and olive trees which you did not plant, and you shall eat and be satisfied, then watch yourself, lest you forget the Lord who brought you from the land of Egypt, out of the house of slavery.
It is always the human tendency when life is going well and we have everything we could ever want in this life, to think that we deserve all this goodness, and that we have somehow earned it; and forget that God is the One Who provides our needs and wants and has brought us through everything in our past in order to make us who we are today. It's easy to forget the past as we enjoy the present.
That's why we're admonished to watch yourself to keep in mind Who God is, and all the rules, regulations, and instructions He has given us so that we can live pleasant lives.
(v. 18) And you shall do what is right and good in the sight of the Lord, that it may be well with you and that you may go in and possess the good land which the Lord swore to give your fathers.
God always fulfills His promises to us. We need to "pay attention" and "be careful" and "watch ourselves" constantly and continually, every day, so as not to slip into the worldly perspectives that surround us all the time, that lie to us and try to deceive us into attitudes and actions that will destroy us.
Even so, come, Lord Jesus!
