Fearing that your parent, whether earthly or heavenly, will kill or torture you for anything, is unhealthy fear.
God is NOT our parent naturally. We are born as children of Adam, not God. Our natures want a God that we can control, a false God. We are his enemy. We, by nature would much rather choose religion (or an ideology) instead of the personage of an infinite God any day. This is what we all did as JW's and we ALL mocked those Christians that we met in field service that adocated a PERSONAL relationship with Christ Jesus.... as if such a thing were impossible for the mere average Joe.
The idea that we should fear a God that will murder us (we're already justly on death row) is insane, irrational, and totally phobic. Only the silliest of minds could entertain such a thought without realizing that we are all dying ANYWAY!!
Death is not to be feared. It is the judgment that occurs after a person has died that is to be feared. There is no escape from the judgment of an infinite God. There is simply no place to hide, even in death.
And fear not them which kill the body, but are not able to kill the soul: but rather fear him
which is able to destroy both soul and body in hell. - Jesus
