From an outside rational observer's standpoint, Christianity is kind of absurd

[Meriweather]

If someone were to come from outer space and saw Christians walking around with crosses around their necks, he would ask....why do they have a method of execution around their necks?

If Jesus was killed in an electric chair, would they have little electric chairs around their neck?

Ah, but the cross is not a symbol of death, but rather triumph over death. It also represents perseverance in adverse circumstances, and obedience even if it leads to death. The electric chair, the hangman's noose, or the rifle do not have these nuances.
