Jesus lived a sinless life
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 horse, which they do. (Mark 11:1-6 tells the same story, but notes that the owners let the disciples take the horse 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.
