The same way the the world confuses love and joy, it has also confused the real meaning of peace. The world wants peace and no more wars... but, even if all the atomic weapons are banned on the face of the earth, even if all the countries were to get along, even then, there would not be peace that humans need and crave.
It's not acquired through a simple sensation of well-being among people, but through a deep stillness in the soul, and is only possible when God, in the Person of His Son Jesus, through the Holy Spirit, passes to reign through your soul.
Peace I leave with you, My peace I give to you; not as the world gives do I give to you. Let not your heart be troubled, neither let it be afraid. (John 14:27) There are two kinds of peace: The peace that comes from God and the peace from the world. The first reaches the depths of a person when the peace of the world only reaches the exterior.
Everything that affects our interior lasts permanently, as it creates inside of us a different world totally independent and private. Exterior peace is subject to and also dependent on others.
You can receive this power of peace that comes from God... open your soul and pour it before the Lord Jesus through a sincere prayer. The Holy Spirit will take care of the rest. Don't waste time! Do it now!
