How can we have peace when half of the people in this world seem to be fighting the other half? Peace is what you feel inside where it might not be visible. You can’t see someone else’s peace until you know them long enough to sense what they are feeling. John 14:27 Peace I leave you, my peace I give unto you not as the world giveth, give I unto you.. Let not your heart be troubled, neither let it be afraid. Jesus made it very clear that He meant for His disciples to have peace in their hearts even when things are rough in other parts of our lives.
