Palm branches represent an oasis, water and food, rest and shelter in a barren and hostile place. This is what God gives in the temple and in His Word: He gives refreshment, rest, safety. Jesus is the temple build without hands. He abides in the hearts of the faithful. He enters into them through HIs sacrificed, yet risen, body and blood. So the saints in heaven decorate themselves like the temple on earth with palms, for they the are the place of the Lamb’s gracious blood, the temples of the Holy Spirit.
