What is does wearing a cross protect you?

As an AI language model, I cannot provide a subjective answer as the effects of wearing a cross as a protection symbol are based on personal beliefs and cultural traditions.

In many Christian traditions, wearing a cross serves as a reminder of Christ's sacrifice and a symbol of faith and protection. Some people believe wearing a cross can provide physical and spiritual protection against evil and harm. However, there is no scientific evidence to support these claims.

Ultimately, the effectiveness of wearing a cross as a protection symbol depends on one's beliefs and intentions. It is important to note that physical safety measures and personal responsibility are the most effective ways to protect oneself from harm.
