1. First you have to consider yourself as a human being to be worthless, wicked, sinful, impure and deserving of death.
2.Next, you have to be convinced that your utter lack of value is deserved! After all, your ancient ancestors ate something they weren't supposed to; so, why shouldn't you be considered a wretch? You carry their DNA!!
3. You must face the fact you are going to die. Then, you must buy the idea that you can escape being dead!
4.Since you are weak, can't trust your mind or your heart, naturally you are expected to correctly identify which of the thousands of competing messeges about salvation are indeed correct and then comply!
5.If you brave those odds and accidentally choose correctly and comply with the necessary rituals and behaviors you get to join a group of equally naive souls who become utterly convinced they are right and everybody else is wrong.
So, in a nutshell, you have to think there is such a thing as inheritable sin and that such a thing demonstrates the justice of a Supreme Being.
On the downside....
If you hear the messege of Jehovah's Witnesses and it doesn't make sense to you--it marks you for destruction (no matter how badly it is presented to you or how unconvincing it seems).
You are better off to remain ignorant until Armageddon and throw yourself upon God's mercy.
