Meanwhile, a crowd of many thousands came together, so that they were trampling on one another. He began to say to his disciples first, ‘Be on your guard against the leaven of the Pharisees, which is hypocrisy.’
Luke 12:1
Large crowds are often dangerous to themselves. Many times in His ministry, Jesus had to manage the issues that come along with large crowds of followers.
Jesus often addressed His disciples specifically, even when a crowd was present or gathering. In this case, He compared the hypocrisy of the Pharisees to leaven. This was a clear comparison for the Jews. They were used to leaven (yeast) being an illustration of evil.
Heavenly Father, thank You for life! It is Your great gift, and eternal life in Christ cannot be compared to anything. It is a joy beyond description! I love You, Father. Thank You! I will praise You forever! In the Name of the Lord Jesus Christ I pray and praise You, Amen.
