Passover Blood, the Door, and the Cross

On the night of Passover, judgment was coming through Egypt. Death would strike every home—but God made a way of escape.
Each household was commanded to take a lamb without blemish, kill it, and place its blood on the doorposts and lintel of the house (Exodus 12). That detail mattered.

The door was the place of entry. God wasn’t looking inside the house to see who was worthy. He looked at the blood applied at the door. When He saw it, judgment passed over.
This wasn’t random—it was prophetic. The blood placed on the two side posts and across the top formed the outline of a cross long before crucifixion existed.

Blood on wood. Public. Visible. Applied by faith.

Centuries later, Jesus would say, “I am the door. If anyone enters by Me, he will be saved” (John 10:9).

The lamb had to be spotless. The lamb had to die. The blood had to be applied.

John the Baptist later pointed to Jesus and declared, “Behold, the Lamb of God who takes away the sin of the world” (John 1:29).

Just like in Egypt, salvation wasn’t earned by what happened inside the house. Deliverance came by trusting what God provided and obeying His word. The Passover lamb was preaching the gospel long before the cross.
