Jesus on his own words in the Gospel of John

“Truly, truly, I say to you, whoever hears my word and believes him who sent me has eternal life. He does not come into judgment, but has passed from death to life. Truly, truly, I say to you, an hour is coming, and is now here, when the dead will hear the voice of the Son of God, and those who hear will live. For as the Father has life in himself, so he has granted the Son also to have life in himself. And he has given him authority to execute judgment, because he is the Son of Man. Do not marvel at this, for an hour is coming when all who are in the tombs will hear his voice and come out, those who have done good to the resurrection of life, and those who have done evil to the resurrection of judgment.” (5:24-29)

“But if you do not believe his writings, how will you believe my words?” (5:47)

“It is the Spirit who gives life; the flesh is no help at all. The words that I have spoken to you are spirit and life.” (6:63)

“Why do you not understand what I say? It is because you cannot bear to hear my word.” (8:43)

“I know that you are offspring of Abraham; yet you seek to kill me because my word finds no place in you.” (8:37)

“Truly, truly, I say to you, if anyone keeps my word, he will never see death.” The Jews said to him, “Now we know that you have a demon! Abraham died, as did the prophets, yet you say, ‘If anyone keeps my word, he will never taste death.’” (8:51-52)

“And I have other sheep that are not of this fold. I must bring them also, and they will listen to my voice. So there will be one flock, one shepherd.” (10:16)

“My sheep hear my voice, and I know them, and they follow me.” (10:27)

“If anyone hears my words and does not keep them, I do not judge him; for I did not come to judge the world but to save the world. The one who rejects me and does not receive my words has a judge; the word that I have spoken will judge him on the last day. For I have not spoken on my own authority, but the Father who sent me has himself given me a commandment—what to say and what to speak.” (12:47-49)

“Do you not believe that I am in the Father and the Father is in me? The words that I say to you I do not speak on my own authority, but the Father who dwells in me does his works.” (14:10)

“If you love me, you will keep my commandments.” (14:15)

“Whoever has my commandments and keeps them, he it is who loves me. And he who loves me will be loved by my Father, and I will love him and manifest myself to him.” (14:21)

“If anyone loves me, he will keep my word, and my Father will love him, and we will come to him and make our home with him. Whoever does not love me does not keep my words. And the word that you hear is not mine but the Father’s who sent me.” (14:23-24)

“Already you are clean because of the word that I have spoken to you.” (15:3)

“If you abide in me, and my words abide in you, ask whatever you wish, and it will be done for you.” (15:7)

“If you keep my commandments, you will abide in my love, just as I have kept my Father’s commandments and abide in his love. These things I have spoken to you, that my joy may be in you, and that your joy may be full.” (15:10-11)

“Remember the word that I said to you: ‘A servant is not greater than his master.’ If they persecuted me, they will also persecute you. If they kept my word, they will also keep yours.” (15:20)

“For I have given them the words that you gave me, and they have received them and have come to know in truth that I came from you; and they have believed that you sent me.” (17:8)

“Then Pilate said to him, “So you are a king?’ Jesus answered, ‘You say that I am a king. For this purpose I was born and for this purpose I have come into the world—to bear witness to the truth. Everyone who is of the truth listens to my voice.'” (18:37)
