But if you don't believe his writings, how will you believe my words?"

 5:37-43 And the Father who sent me has home witness about me. You have never heard his voice, nor have you ever seen his form. You do not have his word dwelling in you, because you do not believe in the One whom he sent. You search the scriptures, because you think that in them you have eternal life. It is they which bear witness about me, yet you refuse to come to me that you may have life. I receive no glory from men; but I know you and I know that you do not have the love of God in you. I came in the name of my Father and yet you do not receive me. If another comes in his own name, you will receive him.
