In Christian symbolism the palm has always been used to represent joy, and especially that joy which comes from victory. Doubtless this symbol came into the church through the use mode of palm branches by the Greek and Romans to celebrate their triumphs over

their enemies. But to Christian the palm symbolizes victory over self and the world. The great multitude of the redeemed are represented as standing before the Lamb, clothed with white robes and with palms in their hands. --J. Burms
