If Jesus rose from the dead, then you have to accept all that he said; if he didn't rise from the dead, then why worry about any of what he said? The issue on which everything hangs is not whether or not you like his teaching but whether or not he rose from the dead.
Many people think of the Bible as a book of moral teachings with stories sprinkled through to illustrate the teachings. But it's a lot BETTER THAN THAT...the Bible is a single true story with teachings sprinkled through to illustrate the story.
To stay away from Christianity because part of the Bible’s teaching is offensive to you assumes that if there is a God he wouldn’t have any views that upset you. Does that belief make sense? If you don’t trust the Bible enough to let it challenge and correct your thinking, how could you ever have a personal relationship with God? In any truly personal relationship, the other person has to be able to contradict you.
