Jesus lived a sinless life
- "We are correct in concluding it is impossible for a person to be sinless, unless that person was also God."
- The Bible states that Jesus was sinless  and there is no record of him committing any sin.
- Humans either have a divine nature or they do not.
- Humans without a divine nature commit sins.
- Therefore Jesus has a divine nature.
Sin is breaking God's law. 1 John 3:4
The Bible is not a reliable source
- Main Article: Biblical inerrancy
The argument assumes the Bible is an accurate record of the life of Jesus. However, it's reliability is questionable at best.
Begging the question
- Main Article: Begging the question
Jesus is recorded to have broken several Jewish laws concerning the Sabbath Mark 3:1-6 , dietary restrictions, ritual washing, etc. The justification for this was he was God and could amend divine laws. However, for this defence to work it must be assumed that Jesus is divine. Matthew 12:8 So, the argument that attempts to establish Jesus was divine depends on the unstated premise that he is divine! This is begging the question.
Biblical record of sins
The gospels contain accounts of Jesus committing sins. At the very least, it is not clear that he never committed any sins.
In Luke 19:29-35 , Jesus tells his disciples to steal a donkey, which they do. (Mark 11:1-6 tells the same story, but notes that the owners let the disciples take the donkey once they found out that it was for Jesus.)
In Matthew 12:46-50 , Mark 3:31-35 , and Luke 8:19-21 , Jesus is preaching to a crowd, when his mother and brothers come looking for him. He denies them, saying, in effect "my followers are my family now."
In Luke 16:1-9 , Jesus tells a parable about a manager who encourages his clients to pay his employer less than they owe. He is commended for acting "wisely".
In Luke 12:47-48 , Jesus advocates the beating of slaves.
There may have been sins that were not recorded since the New Testament did not record every event of his life.
Sin and divinity separate issues
There is no evidence of any correlation between sinlessness and divinity. Job was blameless in the sight of God, yet he too wasn't divine. In fact if it were the case then stating that God created man such that he could not be sinless, is a great immoral act on the part of God.
Jesus admits he sins
In the incident where the divine law condemned a women to be stoned to death, Jesus said "He that is without sin among you, let him first cast a stone at her." John 8:1-11 Even though it was the law for her to be stoned, even Jesus does not throw the first stone because he too sinned.
