One of our members, Neil Glass made the doorframe we see in this picture. The red paint on the doorframe symbolizes the blood of the lamb. On the inside of the house is safety, and the promise of deliverance from bondage. On the outside of the house is judgment, weeping and destruction. The blood of the lamb marks the line between judgment and mercy, destruction and salvation.
Likewise as Christians we believe that the blood of the Lamb of God, Jesus Christ, was suspended between heaven and earth on the cross. Again this blood separates judgment from mercy, destruction from salvation. On this side of the blood of Jesus, there is mercy and salvation. All are invited to find rest on this side of the cross. The whole message can be heard under sermons, The Passover.
Those more historically astute may recognize that the Menorah on the door would not have been there in Egypt. However, the passover feast was celebrated for generations of Jews and continues to be celebrated today, even after Hanukkah. The Menorah on the door reminds us of the continuity between what we call the Old Testament and the New.
