This command is unique from the others. It’s all about what you are thinking, not about what you are doing. If this command is obeyed the others would be so much easier to obey. Boredom can be the beginning of coveting. We are a bored people. We are bored, but we still want more. What are you filling your life with?
God’s goal for us is His peace, His Shalom. He wants Shalom with Him and with others. His aim: to give us a contented spirit, a heart that is pleased with what He has given us. Deep greed seeks more. There is no peace there.
