I think the best thing a person can do is to read through the Gospels in the Bible and really look at Jesus, because if a person does this, they will realize that the Jesus they learned about in Sunday school or the Jesus they hear jokes about or the skinny, Gandhi Jesus that exists in their imaginations isn't anything like the real Jesus at all.
