I lie down in peace and sleep comes at once for you alone, Lord, make me dwell in safety. ~Psalm 4:9
If we depend on God for security and safety, we will never be disappointed. Begin and end your days with the Lord, giving up trials to Him and remain open to what He wants you to learn. Then, peace will come.
