John 16: 33 “I have told you these things, so that in me you may have peace. In this world you will have trouble. But take heart! I have overcome the world.”
I love all of John chapter 16. I can so relate to the disciples feelings of fear, grief, and confusion. First Jesus tells them they may be put to death. Then he tells them he has to leave them, and yet they shouldn’t worry, because they will be receiving an Advocate. I’m sure they were wondering, what is an Advocate? Then he tells them again that he will leave them and they will be filled with grief. But later, he tells them he will return to them and they will rejoice. At the end of all these seemingly contradictory statements, he basically says to them: I’ve got this! In me you will have peace! Take heart!
