「我把平安留给你们，我将我的平安赐给你们；我所赐给你们的，不像世界所赐的一样。你们心里不要烦乱，也不要胆怯。
你们听见了我给你们说过：我去；但我还要回到你们这里来。如果你们爱我，就该喜欢我往父那里去，因为父比我大。
如今在事发生前，我就告诉了你们，为叫你们当事发生时能相信。
我不再同你们多谈了，因为世界的首领就要来到；他在我身上一无所能，
但为叫世界知道我爱父，并且父怎样命令我，我就照样去行；起来，我们从这里走罢！」
Friends, in today’s Gospel Jesus gives us an antidote for fear. Whom or what are you afraid of? That is a very important spiritual question. One way to understand our lives is to look at those things that we seek: wealth, power, privilege, honor, pleasure, friendship. But another way is to turn that question around and determine what or who it is that we fear.
We might fear the loss of material things, the loss of a job, the loss of physical health, the loss of the esteem of others, the loss of personal intimacy, or ultimately, the loss of life itself. We are afraid of many things, but I’d be willing to bet that there is a primary or principal fear. What is it for you?
Now, after identifying that, listen to Jesus: "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." Any and all of the things that we customarily fear—loss of money, fame, pleasure, and power—have to do with this world. What Jesus is saying is that we should not let those fears come to dominate or define our lives, for he is with us—and with him is his peace.
