How do atheists see Jesus' parables?

[Chad32]

Like any stories, you can sometimes learn morals from them. Though some lessons will be outdated or backwards. Like the story of the man who builds his house on sand, and another o rock. You're meant to come away thinking faith is the rock, but the need for revivals shows that faith is not a rock.

That particular story is rather odd. Who kills or abuses people just for being invited to a wedding? And why would you tie someone up before throwing him out the door, instead of just asking him to leave and come back with better clothes? Actually, who prepares a wedding before invitations are even sent?

I assume the wedding represents heaven, but I don't really know what moral we're supposed to take from it.
