Then came the day of Unleavened Breadon which the Passover lamb had to be sacrificed. Jesus sent Peter and John, saying, “Go and make preparations for us to eat the Passover.” Luke 22:7-8
The Festival of Unleavened Bread was a week-long party to commemorate the time God freed the Jews from slavery in Egypt. God told the people to get up and get out… And not to even wait for the bread to rise in the oven. Because of the urgency of the instruction, the people were to celebrate their deliverance by eating bread with no yeast—unleavened bread.
In fact, many Jewish families had the tradition of going through the home the night prior to the Festival and eradicating yeast from them. The children would be part of the process, learning the from a young age the difficulty of cleansing a home of yeast.
Yeast is so fine and dust-like that when you try and sweep it up or toss it out, the particles remain in creases, or cling to surfaces, or float in the air. It can be frustrating, but that’s the point.
In scripture, yeast is sometimes a parallel for sin, suggesting that once it’s in the house, it’s impossible to get completely out. And yeast is in the house.
Perhaps you can related to the famous Apostle Paul,
“Oh, what a miserable person I am! Who will free me from this life that is dominated by sin and death? Thank God! The answer is in Jesus Christ our Lord.” -Romans 7:24-25
