Why was there no book in the Bible authored by Jesus himself?

Answer 1

Jesus is the Word. He is the author. Let's look at what The Bible tells us.

God can not lie. Titus 1:2

You killed the author of life, but God raised him from the dead. We are witness of this. Acts 3:15

...should make the author of their salvation perfect through suffering." Hebrews 2:10

For the Word of God is living and active. Hebrews 4:12

...and His name is the Word of God. Revelation 19:13

For the Father has life in himself, so he granted the Son to have life in himself. John 5:26

The seed is the Word of God. Luke 8:11

The Son is the radiance of God's glory and the exact representation of his being, sustaining all things by his powerful word. Hebrews 1:3

When you received the Word of God, which you heard from us, you accepted it not as the word of men, but as it actually is, the Word of God, which is at work in you who believe. 1 Thessalonian 2:13

In the beginning was the Word and the Word was with God, and the Word was God. John 1:1

For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one. 1 John 5:7

This is what we speak, not words taught us by human wisdom but in words taught by the Spirit, expressing spiritual truths in spiritual words. 1 Corinthians 2:13

So you see that it is very clear Jesus is the Word.

Further Study:

The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the one and only, who came from the Father, full of grace and truth. John 1:14

Consequently, faith comes from hearing the message and the message heard through the word of Christ. Romans 10:17

Jesus said, He was the first and the last. Revelations 1:17-18

Jesus is God manifested in the flesh. Timothy 3:16

There is but one Lord. Isaiah 45:18; Ephesians 4:5

Christ is the Lord. Luke 2:11

Jesus is the true God. 1 John 5:20

Jesus said, "I and my Father are one." John 10:30

Answer:

According to the credits of the last book in the Bible, it is Jesus' personal dictation to His angel, who revealed it to John, who then recorded it.

"The revelation of Jesus Christ, which God gave Him to show His servants what must soon take place. He made it known by sending His angel to His servant John, who testifies to everything he saw -- that is, the Word of God and the testimony of Jesus Christ." (Rev.1:1-2 NIV)

Revelation isn't "John's Revelation"... but the "Revelation of Jesus Christ" -- which makes John kind of Jesus' "Holy Ghost" writer =-]

Answer 2

Is it because Jesus did not really exist? Is it because Jesus was a wandering holy man who was illiterate and therefore could not write? Jesus did not write a gospel story about himself, but neither did Matthew, Mark, Luke or John, in spite of later tradition. All the New Testament gospels were originally anonymous and so they could have been written by anyone in the hundred years since Jesus' death, but scholars do know that they were not written by eyewitnesses to the events they portray.
