Take Heed and Beware

Summary

The sermon emphasizes the importance of heeding and being wary of the 'leaven' in the church, which symbolizes false doctrine, moral laxity, and improper practices. It draws from Matthew 16, 1 Corinthians 5, and Galatians 5 to illustrate how these issues can silently and invisibly spread like yeast, undermining the church's purity and discipline. The preacher warns against complacency and stresses the need for vigilance in doctrine, discipline, and practice to maintain the church's integrity.
