Deuteronomy 8 is a call to remember God as the source of our blessings.  Worship is the disciplined act of remembering.  Without it, God is out of sight and out of mind.  He brought us out of the house of slavery.  He gives us power to earn a living.  Abundance can lull us into thinking “by my hands I acquired this”.  Forgetfulness can take us to exile.  Remembering keeps the commandments which expresses gratitude and worship.

“Beware that you do not forget the Lord your God by not keeping His commandments and His ordinances and His statutes which I am commanding you today; otherwise, when you have eaten and are satisfied, and have built good houses and lived in them, and when your herds and your flocks multiply, and your silver and gold multiply, and all that you have multiplies, then your heart will become proud and you will forget the Lord your God who brought you out from the land of Egypt, out of the house of slavery.” Deuteronomy 8:11-14 (NASB)
