“Be careful,” Jesus said to them. “Be on your guard against the yeast of the Pharisees and Sadducees.”…
…Then [Jesus’ disciples] understood that He was not telling them to guard against the yeast used in bread, but against the teachings of the Pharisees and Sadducees.
— Matthew 16:6-12
Why does Jesus use such cautious language like “be careful” and “be on guard” when talking about false teaching? It’s because false teaching has an appeal to it, especially when it is so close to the truth. The Pharisees and Sadducees were reading from the same scriptures as Jesus, yet coming up with conclusions that were contrary to the truth. Sometimes false teachings can be more dangerous when they close to the truth; and if you know nothing, you will believe anything.
Developing a healthy, biblical, theological framework will help prevent you from being deceived by false teaching. Start building your theology based on the scriptures as a whole. Develop a healthy, consistent reading plan and cover it with prayer and obedience. Read the bible book by book, verse by verse, and ask the Holy Spirit to enlighten your understanding.
Heavenly Father, teach me your word. Enlighten my understanding of the scriptures, so that I can be on guard against false teachings. Help me discern the difference between truth and error so that I would choose the side of truth, in Jesus’ Name I pray, AMEN!
