Hebrew Bible and Christian Scriptures

In Deut. 6, Moses says, “you shall love the Lord your God with all your heart, and with all your soul, and with all your might” In verses 7-9, Moses tells the people to remember and teach this to their children and celebrate what the Lord has done.   What does this mean for us today?  What does this mean for the Israelites?  What do it mean for us today?  Where is the disconnect between the two situations?
