Jesus said to his disciples: "Peace I leave with you; my peace I give to you. Not as the world gives do I give it to you. Do not let your hearts be troubled or afraid.” (Jn 14:27-31a)

Peace. The Shalom of God. This is one of the most beloved passages of the gospels. Even though we receive the peace from above, it doesn’t mean there won’t be problems, which is why the Lord adds: "Do not let your hearts be troubled or afraid." Our faith is in the One God has sent. As Saint Augustine said, "Our hearts are restless until they rest in you."
