"The Feast of Unleavened Bread is a reminder of God's miraculous deliverance from Egyptian bondage, for when Israel fled from Egypt in the middle of the night, there was no time for bread dough to rise. So, the Lord commanded, "seven days you shall eat unleavened bread with it, that is, the bread of affliction (for they came out of Egypt in haste), that you may remember the day in which you came out of the land of Egypt all the days of your life. [Dt 16:3 & Ex 12:39]In Hebrew, leaven is known as "hametz," which literally means "sour." Leaven (usually yeast or baking powder) is used to produce fermentation, especially in bread dough. As leaven sours the dough, tiny gas bubbles are produced which cause the dough to rise. Not only is the eating of leavened foods (such as breads and rolls) forbdden during the Feast of Unleavened Bread, but even the presence of leaven within one's house is unlawful. Sin is often pictured as leaven in Scripture (Mt 16:6,11; Mk 8:15; Lk 12:1; Gal 5:9). The ancient rabbis also believed that "leaven represents the evil impulse of the heart." Leaven is well-suited as a picture of sin since it rapidly permeates the dough, contaminating it, souring it, fermenting it, and swelling it to many times its original size without changing its weight. In fact, this souring process (the first stage of decay) is operative solely because of the curse of death decreed by God when Adam sinned. Sin leaven pictures sin, only unleavened bread (matzah) was used in the Temple. Offerings had to be pure, and anything leavened was deemed impure and unfit." Jesus, the Christ, is the freedom from sin's leaven. What are you going to do with His freedom? Will you keep adding the sin to your lives, or will you remove it so you can get away quickly?
