The man answered, “‘Love the Lord your God with all your heart, all your soul, all your strength, and all your mind.’ Also, ‘Love your neighbor the same as you love yourself.’”
“Now, Israelites, listen! What does the Lord your God really want from you? The Lord your God wants you to respect him and do what he says. He wants you to love him and to serve the Lord your God with all your heart and with all your soul.
And you must love God with all your heart, all your mind, and all your strength. And you must love others the same as you love yourself. These commands are more important than all the animals and sacrifices we offer to God.”
Why is this true? Because anyone whose thinking is controlled by their sinful self is against God. They refuse to obey God’s law. And really they are not able to obey it.
