It is true that he was weak when he was killed on the cross, but he lives now by God’s power. 2 CORINTHIANS 13:4
The cross. Can you turn any direction without seeing one? Perched atop a chapel. Carved into a graveyard headstone. Engraved in a ring or suspended on a chain. The Cross is the universal symbol of Christianity. An odd choice, don’t you think? Strange that a tool of torture would come to embody a movement of hope. The symbols of other faiths are more upbeat: the six-pointed star of David, the crescent moon of Islam, a lotus blossom for Buddhism. Yet a cross for Christianity? An instrument of execution? …
Why is the Cross the symbol of our faith? To find the answer look no farther than the cross itself. Its design couldn’t be simpler. One beam horizontal—the other vertical. One reaches out—like God’s love. The other reaches up—as does God’s holiness. One represents the width of his love; the other reflects the height of his holiness. The Cross is the intersection. The Cross is where God forgave his children without lowering his standards.
