Hear, O Israel: The Lord our God, the Lord is one. You shall love the Lord your God with all your heart and with all your soul and with all your might (Deuteronomy 6:4-5).
When God revealed Himself through His prophet Moses, God described Himself. He said that He is one God, not many “gods.” The one and only God deserves all of our love, not just a part of it.
Confirmed By Jesus
When Jesus, the Prophet like Moses, came, He drew special attention to these verses from the sixth chapter of Deuteronomy. A leader asked Jesus about the most important command of the Law. Mark 12:29 reports Jesus’ reply:
”The most important is, ‘Hear, O Israel: The Lord our God, the Lord is one. And you shall love the Lord your God with all your heart…’ ”
Jesus continued then to quote from God’s message in Deuteronomy 6. This truth is the foundation for all God’s other commands. If many gods had made us, they might all have a right to our love. But the greatest fact of God is that He is one. One alone created us! One alone gives us life! One alone, therefore, has the right to our love. That leads to the greatest command, that our whole heart, soul, mind and strength should go to Him alone.
