Jesus said to his disciples: now I am going to the one who sent me, and not one of you asks me, 'Where are you going?'
But because I told you this, grief has filled your hearts.
But I tell you the truth, it is better for you that I go. For if I do not go, the Advocate will not come to you. But if I go, I will send him to you.
And when he comes he will convict the world in regard to sin and righteousness and condemnation: sin, because they do not believe in me; righteousness, because I am going to the Father and you will no longer see me; condemnation, because the ruler of this world has been condemned.
