We often see people who wear cross-shape earrings or necklaces. Through a world-wide famous movie 'The Passion of the Christ,' we can find that a cross was a really heavy thing intended for the death penalty. Jesus, Son of God, had no sin at all, but He died on the cross to redeem us from sin. And He gave eternal life to those who believe in Him as the Savior. That is why a cross is not a simple accessory or a thing for death penalty, but the glorious symbol of salvation.
"For the word of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God." (1 Corinthians 1:18)
