Jesus gave His disciples His peace. Every born again believer receives the same gift. It is irrevocable. That means that no matter what circumstances we are in, His peace abides. What happens when we don’t feel peaceful? We broke the condition.
Isaiah 26:3 says, “You will keep him in perfect peace, whose mind is stayed on You, because he trusts in You.” We lose our sense of peace when we allow our thoughts to stray. His peace never leaves, we just cover it over with debris type thoughts.
Note the second part of the condition. It is trust. The foundation for perfect peace is trust. Proverbs 3:5 says that we are to trust the Lord with all of our hearts. However when we give it over to thoughts of fear, anxiety, worry, anger, bitterness, or unforgiveness, we cover over what is there.
