Here's where I stand:
we live in a created universe,

we have a creator who loves us,

he sent his son to die for our sins,
X
in order to get to heaven we have to have a relationship with Jesus.
X
Christianity is not a building or a practice, it's a relationship.
Do I qualify? By the way, I don't know any *human* parent who would force their child to suffer a horrible death and die for the sins of their siblings, do you? Why would a gracious deity abuse their child like that? I don't believe in the atonement doctrine. At all.
Also, I think there is a lot of forgiveness and we can get to 'heaven' (whatever each of us indivdiually thinks that is) without giving ourselves over to "Jesus" in this life. JMO.
