Deuteronomy is an interesting book, it is written by Moses to the Israelites. He is writing their history, a journal of sorts to remind them of everything they have been through. Because, let's be honest, they were very forgetful people.
We see in chapter 8 Moses is specifically telling them “DO NOT FORGET!”
2 Remember how the Lord your God led you all the way in the wilderness these forty years, to humble and test you in order to know what was in your heart, whether or not you would keep his commands. 3 He humbled you, causing you to hunger and then feeding you with manna, which neither you nor your ancestors had known, to teach you that man does not live on bread alone but on every word that comes from the mouth of the Lord.
Again in verse 11:
11 Be careful that you do not forget the Lord your God, failing to observe his commands, his laws and his decrees that I am giving you this day.
And again verse 18 and 19:
18 But remember the Lord your God, for it is he who gives you the ability to produce wealth, and so confirms his covenant, which he swore to your ancestors, as it is today. 19 If you ever forget the Lord your God and follow other gods and worship and bow down to them, I testify against you today that you will surely be destroyed.
We as humans can be very forgetful, especially when it comes to our Father. He continues to bless us, giving us breath everyday, and yet we forget. Our Lord and Savior has only asked that we love and serve him with all our hearts and souls
Deuteronomy 10:12 And now, Israel, what does the Lord your God ask of you but to fear the Lord your God, to walk in obedience to him, to love him, to serve the Lord your God with all your heart and with all your soul,
Remember today what the Lord has commanded you; remember His love, His sacrifice, His commands. He has already taken care of all your needs, as long as you continue to follow Him.
