Jesus spoke everything the Father commanded. The Holy Spirit teaches you what Jesus said.

“And I know that His command is everlasting life. Therefore, whatever I speak, just as the Father has told Me, so I speak.” (Jn 12:50)
“But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you.” (Jn 14:26)
“However, when He, the Spirit of truth, has come, He will guide [hodegeo] you into all truth; for He will not speak on His own authority, but whatever He hears He will speak; and He will tell you things to come.” (Jn 16:13)
“When you lift up the Son of Man, then you will know that I am He, and that I do nothing of Myself; but as My Father taught Me, I speak these things.” (Jn 8:28)
“I speak what I have seen with My Father, and you do what you have seen with your father.” (Jn 8:38)
“Do you not believe that I am in the Father, and the Father in Me? The words that I speak to you I do not speak on My own authority; but the Father who dwells in Me does the works.” (Jn 14:10)
“And I will pray the Father, and He will give you another Helper, that He may abide with you forever—“the Spirit of truth” (Jn 14:16,17)
“But when the Helper comes, whom I shall send to you from the Father, the Spirit of truth who proceeds from the Father, He will testify [martureo] of Me. And you also will bear witness [martureo], because you have been with Me from the beginning.” (Jn 15:26-27)
