I’ve been speaking through the book of Exodus for the last several months. It has been an awesome study for me. I just love the Old Testament and I have several really good professors at Reformed Theological Seminary for that. Ralph Davis always taught me that God was the main character in the Old Testament. John Currid helped me to see some things in the Old Testament that I never have seen. In my studies I’ve leaned a lot of Ligon Duncan, who taught me theology and is now the pastor of First Presbyterian Church in Jackson, MS. I owe a lot to all of these men.
We have been studying the plagues of Exodus and are about to come upon the last and most deadly one of them all. Before it happened God instituted the Passover and the Feast of Unleavened Bread. In both He gave very detailed instructions on what to do with both of these ordinances. God was coming to Egypt in an amazing way in this last plague. Israel was to be prepared and prepare for his visit much like we prepare for the company of guests in our own homes. Two things really come out in this Scripture to me. One, God never wants them to forget that He redeemed them from the slavery of Egypt. God doesn’t want you and me to forget that He has saved us either. The second things that pops out at me is that God wanted them to be holy in preparation for his coming. That is the whole thrust of the Feast of Unleavened Bread. It is clear in the Scripture that leaven represents sin. Jesus said: Luke 12:1 (ESV) “In the meantime, when so many thousands of the people had gathered together that they were trampling one another, he began to say to his disciples first, “Beware of the leaven of the Pharisees, which is hypocrisy.” Paul spoke of it: 1 Corinthians 5:6-8 (ESV) ”Your boasting is not good. Do you not know that a little leaven leavens the whole lump? Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed. Let us therefore celebrate the festival, not with the old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth.” Leaven consisted of leftover dough from a batch of bread baking. They would use it much like ladies use starter today in the making of sour dough bread. Inside that piece of unused dough would be the makings of what would help make the next batch rise.
In the Feast of Unleavened bread they were to eat unleavened bread for seven days. If they ate anything leavened then they were to be cut off from the nation. God was serious about this. In order for them to make sure that they didn’t have any leaven in their bread they were to do a thorough cleaning in the house first. There was to be nothing leaven in the house.
God wanted something even greater in the lives of the Israelites. He wanted them to remove the sin in their lives. All of it. They were to leaven none of it. They were to make a clean sweep because even the least amount of leaven will spread. The least little sin will do the same. Sin has a way of spreading and little sins snowball on us in a hurry.
We have begun a 21 day fast at our church. Different people are fasting various items. Some are not eating any kind of meat. Others are fasting TV. Some are fasting sweets. I jokingly told everyone that I was fasting cow tongue and tripe. I am fasting something in my life right now. Please pray for me.
What do I want out of this fast? I want a clean sweep. I want God to remove the little areas of compromise and sin that I have allowed to come into my life. I desire holiness and I desire a deeper and more committed relationship with my wife during this time. I believe that God is just as serious about my and your holiness as He was about Israel’s. So tell me…is there anything that you need to clean up?
I end with a quote from Philip Ryken who has been a tremendous blessing for me in this study:
“Even a small sin is dangerous because, like yeast, it wants to spread. This is why God has a zero-tolerance policy when it comes to sin. Anyone who thinks that some sins can be tolerated misunderstands the whole meaning of salvation. God delivered us from our bondage so that we would make a clean sweep.
Every believer needs to apply this personally. Is there a sin that you have decided to tolerate? Are you nursing a private grudge or indulging a secret lust? Is there something you have decided that it is all right for you to take, even though it doesn’t actually belong to you? Do you think that worry and impatience are not really sins but just bad habits? Is there some area of your personal life where you have decided that it is okay to be undisciplined?
Perhaps you think that it is only a small sin. Perhaps from time to time you tell yourself that you will start to do something about it once it starts to get out of control. If that is what you are doing, then you are in great spiritual danger because sin is like yeast: Once it gets into your life, it will keep growing and spreading until it corrupts everything. Before that happens, God’s Word has something very simple and very straightforward to say about that sin: “Get rid of it!””
