You are mistaken. Since He is the Word, the entire text of the Bible comes from Him. The Holy Spirit teaches all things that come from Christ. That would be His indirect message, All SCRIPTURE: all 66 books from some 40 authors over 1600 years.
Pertaining His death and resurrection, here are a few words we know were quoted within His 3 1/2 year ministry
(* of which only a fraction has been written down).
Matt. 17:22-23 Now while they were staying in Galilee, Jesus said to them, “The Son of Man is about to be betrayed into the hands of men, and they will kill Him, and the third day He will be raised up.” And they were exceedingly sorrowful.
Matt. 20:18-19 Behold, we are going up to Jerusalem, and the Son of Man will be betrayed to the chief priests and to the scribes; and they will condemn Him to death, and deliver Him to the Gentiles to mock and to scourge and to crucify. And the third day He will rise again.
Mark 14:28 But after I have been raised, I will go before you to Galilee.”
Luke 9:22 saying, “The Son of Man must suffer many things, and be rejected by the elders and chief priests and scribes, and be killed, and be raised the third day.”
Luke 18:31-33 Then He took the twelve aside and said to them, “Behold, we are going up to Jerusalem, and all things that are written by the prophets concerning the Son of Man will be accomplished. For He will be delivered to the Gentiles and will be mocked and insulted and spit upon. They will scourge Him and kill Him. And the third day He will rise again.
John 2:19-22 Jesus answered and said to them, “Destroy this temple, and in three days I will raise it up.”
Then the Jews said, “It has taken forty-six years to build this temple, and will You raise it up in three days?”
But He was speaking of the temple of His body. Therefore, when He had risen from the dead, His disciples remembered that He had said this to them; and they believed the Scripture and the word which Jesus had said.
Matthew 26:28 For this is My blood of the new covenant, which is shed for many for the remission of sins.
* John 21:25 Now there are also many other things that Jesus did. Were every one of them to be written, I suppose that the world itself could not contain the books that would be written."
imagine if all Jesus' words that were verbally spoken, were written down.
We see a red letter edition with about 31,000 words of Jesus. Technically how much teaching is that? Speaking very slowly, that's only about 5 hours of sermons. He could cover that much in one day. Imagine if he only taught the disciples for one hour/day for 3 1/2 years, He would speak 25 times the amount written down. Likely, He talked and answered questions of 12 curious students all day long ... and questions about the mysteries never revealed - only if we could take a peak at those answers omitted and sealed.
