The second part of Moses farewell address to the Israelites began with a review of the Ten Commandments. They were a brief summary of the complete Law of Moses. Some have suggested that God condemns children and future generations for the sins of their parents. This is true only to the extent that succeeding generations are influenced by the examples of their ancestors. Each person is accountable for his own actions, whether good or bad and cannot be lost or saved because of the sins or obedience of anyone else.
“Hear, O Israel: The Lord our God, the Lord is one!” The “great commandment” summarizes man’s complete relationship with God. Failure to observe any command from Him is a failure to completely observe, “You shall love the Lord your God with all your heart, with all your soul, and with all your strength.”
As the Israelites were about to enter the Promised Land, it was important for them to remember to conduct themselves as God’s children and to teach their own children to be obedient to Him. They were entering a difficult phase of their lives. Men have a tendency to become like their neighbors. The Canaanites and other nations about them worshipped false gods. That would be highly displeasing to God.
