"Going to church doesn't make you a Christian any more than going to the garage makes you a car." - Laurence Peter
I would like to add something similar, in direct refutation of one of the major doctrines of many Protestant denominations:
"Saying you accept Jesus (confessing His name) doesn't make you an actual disciple of Christ any more than saying you accept a doctor actually cures you of anything."- Papa D
At some point, you have to do what they tell you to do in order to be serious about your acceptance of them and be healed.
