Today's reading shows Jesus promising his disciples (including us) peace. That doesn't mean we'll avoid trouble, but it means ultimately, God's peaceful kingdom will come.
25”I have said these things to you while I am still with you. 26But the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you everything, and remind you of all that I have said to you.27Peace I leave with you; my peace I give to you. I do not give to you as the world gives. Do not let your hearts be troubled, and do not let them be afraid.
28You heard me say to you, ‘I am going away, and I am coming to you.’ If you loved me, you would rejoice that I am going to the Father, because the Father is greater than I. 29And now I have told you this before it occurs, so that when it does occur, you may believe. 30I will no longer talk much with you, for the ruler of this world is coming. He has no power over me; 31but I do as the Father has commanded me, so that the world may know that I love the Father. Rise, let us be on our way.
