Read 1 Corinthians 5:6-13.

Sin in the church is not only about the sinner; it affects everyone. The Corinthians had an unrepentant sinner in their ranks, and rather than dealing with the sin, they were tolerating it (see 1 Corinthians 5:1-2). Paul said they were even “boasting” about it (v. 6)! This one person’s sin was changing the whole church; in pride, they were now calling “good” what God called “evil.”

Paul compares sin in the church to yeast in a lump of dough. In Exodus, when the Israelites were leaving Egypt, God told them not to leaven their bread—there was no time because their rescue was coming quickly. Even now, at Passover many Orthodox Jews will search for any yeast in the house to get rid of it. It’s a symbolic ritual: Yeast represents the old way of life under slavery. The Corinthian Christians were never slaves in Egypt, but they were once slaves to sin—until Christ set them free. That is why Paul told them to get rid of the “yeast,” the sin in their midst.

So seriously did Paul want these believers to treat sin that he desired them not to associate with or even share a meal with unrepentant sinners in the church (see 1 Corinthians 5:9, 11). Christians must see sin for what it is—the way to bondage and death—so that we cling to Christ, humbly rejecting sin and living in the freedom He has won for us. 

Prayer: Lord, help me to see the sin in my life, that I might repent, remembering the freedom You have purchased for me with Christ’s blood. Help me to walk humbly before You in righteousness. I pray in the name of Jesus. Amen.

“Your boasting is not good. Don’t you know that a little yeast leavens the whole batch of dough?” (1 Corinthians 5:6).

About The Author

Dr. Michael Youssef, Ph.D.

Even before he was born, it is clear that God had a vision for Michael Youssef. His mother was in poor health when she became pregnant with Michael, and because his life was in danger at the time of birth, the doctor recommended terminating the pregnancy. An abortion was scheduled. But God intervened and sent the family pastor to reassure them that God was involved in this pregnancy. He told them not to be afraid and that the child would be "born to serve the Lord." Michael's parents accepted the pastor's message as a message from God and obeyed. His mother gave birth, and lived to see him give his life to the Lord at the age of sixteen.


Believing that God had called him out of Egypt, Michael sought an exit visa in a time in which no university student was allowed to have a passport or leave the country. God intervened again, and miraculously he managed to acquire a visa. He immigrated to Australia, where he studied at Moore Theological College in Sydney, was ordained as a pastor, and met Elizabeth who became his wife.


The Youssefs came to America in 1977, and in 1978 Michael received a master's degree in theology at Fuller Theological Seminary in California. Then he earned a doctorate in social anthropology at Emory University in Atlanta, Georgia. Michael served nearly ten years in the Haggai Institute, traveling around the world more than 32 times, teaching courses in evangelism and leadership. He rose to the position of Managing Director at the age of 31 years. The family settled in Atlanta, and in 1984, Michael became a citizen of the United States, making his dream of many years come true.


He founded The Church of The Apostles in 1987 with fewer than 40 adults with the mission of "Equipping the Saints and Searching for the Lost". The church has since grown to be a congregation of over 3,000 people today. This church has driven the international ministry of Leading the Way. While it is heard by millions at home and abroad, behind every message preached through radio waves, is the heart of a pastor, willing to nurture and care for these people. Clearly God has uniquely equipped Dr. Youssef to speak to a global audience. The path he has taken has given him an understanding and firm grasp of the Scriptures that transcend cultures. He preaches, teaches and calls with a sincere, based on the authority of the inerrant, inspired Word of God. With his personal knowledge of the Holy Land, its history and culture, Dr. Michael Youssef transmits life to listeners all over the world.
