30 I and the Father are one."
31 The Jews picked up stones again to stone him. 32 Jesus answered them, "I have shown you many good works from the Father; for which of them are you going to stone me?" 33 The Jews answered him, "It is not for a good work that we are going to stone you but for blasphemy, because you, being a man, make yourself God." 34 Jesus answered them, "Is it not written in your Law, 'I said, you are gods'? 35 If he called them gods to whom the word of God came—and Scripture cannot be broken— 36 do you say of him whom the Father consecrated and sent into the world, 'You are blaspheming,' because I said, 'I am the Son of God'? 37 If I am not doing the works of my Father, then do not believe me; 38 but if I do them, even though you do not believe me, believe the works, that you may know and understand that the Father is in me and I am in the Father." 39 Again they sought to arrest him, but he escaped from their hands.
