Deuteronomy 11:1 Therefore thou shalt love the LORD thy God, and keep his charge, and his statutes, and his judgments, and his commandments, alway.
Deuteronomy 11 emphasizes that obedience to God's commands results in blessings like a prosperous land with rain and successful harvests, while disobedience brings curses and divine anger, including droughts. The chapter highlights the importance of parental instruction to pass God's laws to the next generation and serves as a reminder of God's power and past miracles to motivate faithful living. Moses presents a fundamental choice between blessing and curse, which the people will later proclaim.
Therefore you shall love the LORD your God: God commanded Israel to love Him. Love is not a matter left entirely up to the impulses or feelings of God's people. People choose to love the LORD or to not love Him. Additionally, this is a reminder of what the LORD really wants from His people - their love. We could give God a hundred other things, but none of it really matters unless we also give Him our love. As Jesus said to the Ephesian church in Revelation 2:4: I have this against you, that you have left your first love. To lose love is to lose everything.
Keep His charge, His statutes, His judgments, and His commandments: Those who love God will want to please Him, and to honor God as He has revealed in His word. To whatever extent a person fails to obey God, it can also be said that they are lacking in their love for Him. As Jesus said in John 14:15: If you love Me, keep My commandments. Real love for Jesus will be seen in obedience.
So, Deuteronomy 11:1 emphasizes the call to "love the LORD your God and keep his charge, his statutes and his laws always" is a consequence of God's great works and love for Israel for all mankind. This command is a reminder that love for God should be expressed through constant and joyful obedience to all His laws, not just as a feeling but as a life of submission that also involves diligently teaching these laws to the next generation.
He calls not for just occasional or sporadic obedience but a continuous and faithful observance of God's commands. The Hebrew word for "keep" (shamar) implies careful observance and guarding of these laws. True love for God is demonstrated through this unwavering obedience. It's a love that motivates a consistent and willing submission to God's will, rather than just an emotion. The "alway" emphasizes that this commitment to God is not temporary but is to be a way of life for all their days.
