I. Sin must never be glorified

A. The church was “puffed up” (1 Corinthians 5:2)

II. A little leaven

A. The sin of Achan led to the defeat at Ai (Joshua 7:1, 11-13)
B. The sin of Saul caused his family to lose the kingdom (1 Sam. 13:8-14)
C. The principle in prophecy (Haggai 2:11-14)

III. What shall we do?

A. Purge out the old leaven—remove the influence of sin! (Eph. 5:11)
B. You are a new creation in Christ, which means the old things have passed away (2 Corinthians 5:17)
C. Acknowledge sin, confess it to God, beg for His forgiveness (Psalm 51:1-4)
