from the Gospel of John, Chapter 16:
27 for the Father himself loves you, because you have loved me and have believed that I came from God. 28 I came from the Father and have come into the world, and now I am leaving the world and going to the Father.
33 I have said these things to you, that in me you may have peace. In the world you will have trouble. But take heart; I have overcome the world.
