John 14:27

Peace I leave with you; My (perfect) peace I give you; not as the world gives do I give you. Do not let your heart be troubled, nor let it be afraid. (Let My perfect peace calm you in every circumstance and give you courage and strength for every challenge).

If there isn’t peace in our lives than we are not trusting in the Lord. If we are not sleeping or troubled, we are trying to carry a burden that is for Jesus. When thoughts come to our mind against the word of God and His peace caste them down. Let scripture spoken out loud answer the thoughts.
