You don't have to be scared of this world, because in the Gospel, when Jesus talks about what he came to bring to Earth, he used language just as strong.
Society must learnfrom this exampleof Christ! We all need to receive forgiveness. But God tell us in the bible:"When He forgives, He forgets!" And if I say: "This man is a sinner, he did that!" I'm sinning! Because when He forgets, who am I not to forget?
