Furthermore, besides their lying, habitual liars typically have other character flaws. They don't have the dignity and authority that the historical records ascribe to Jesus of Nazareth. Jesus of Nazareth was selfless and consistently served others. Logically, Jesus cannot be a liar. As to Jesus being deluded, the same basic argument could be used.
Lunatics typically exhibit warped personalities and abnormal behavior.
Some deluded people have thought that they were God, but they have shown unbalanced and even schizophrenic behavior patterns. Jesus was always composed and in control of Himself. Although some of the Jews thought that Jesus was insane and even attributed His radical statements and powerful works to demonic sources, others realized that the character of Jesus was hardly the character of a lunatic. Furthermore, people tend to stay their distance from lunatics, but people followed Jesus in great numbers. Even little children were attracted to Him.
