Stressed in these three verses to not eat leavened bread during this time. Not only to not eat it but not to allow it in the house. Leaven is represented in the Bible as a type of sin. Representing haughtiness and the pride of life that puffs us up. The Jewish people were expected to remove all traces of (sin) leaven for seven days, as they remembered their deliverance from bondage and sin.
What would happen if as Christians we took seven days out of the year to remove all traces of sin from our houses? Could we make it seven days without; television, video games, computer, phones and many other things? Not that any of these things are sinful in themselves, but they can easily become objects that come between us and our time with God.
Do any of the items listed above take more of your time than the amount of time you spend with God? This is how they can become obstacles and even sinful. If we spend more time with these objects than with God then they become little gods to us. My challenge to you is to test yourself and take one or more of the items listed and remove them from your life for seven days. Replace that time with time in prayer or the Word. We should always remember what we were delivered from and be careful not to allow those very things to again enslave us.
