Will hanging a cross at home protect people?

True faith is in the heart. It's inside and it's outside. Without faith, the cross is just a handicraft.

What is tangible outside is an expression of the heart. Just as lovers send roses, they convey love. Would you accept it if there was no true love?

So the cross can protect people. Its real value is because Jesus saved mankind through the cross. You should pray to Jesus in front of the hanging cross. He will protect you.
