The Pharisees and Sadducees came to Jesus and tested him by asking him to show them a sign from heaven.
2 He replied, “When evening comes, you say, ‘It will be fair weather, for the sky is red,’ 3 and in the morning, ‘Today it will be stormy, for the sky is red and overcast.’ You know how to interpret the appearance of the sky, but you cannot interpret the signs of the times.[a] 4 A wicked and adulterous generation looks for a sign, but none will be given it except the sign of Jonah.” Jesus then left them and went away.
5 When they went across the lake, the disciples forgot to take bread. 6 “Be careful,” Jesus said to them. “Be on your guard against the yeast of the Pharisees and Sadducees.”
7 They discussed this among themselves and said, “It is because we didn’t bring any bread.”
8 Aware of their discussion, Jesus asked, “You of little faith, why are you talking among yourselves about having no bread? 9 Do you still not understand? Don’t you remember the five loaves for the five thousand, and how many basketfuls you gathered? 10 Or the seven loaves for the four thousand, and how many basketfuls you gathered? 11 How is it you don’t understand that I was not talking to you about bread? But be on your guard against the yeast of the Pharisees and Sadducees.” 12 Then they understood that he was not telling them to guard against the yeast used in bread, but against the teaching of the Pharisees and Sadducees.Matthew 16:1-12 (NIV)
One of the blessings and curses of the time in which we live is the internet. With the introduction of the worldwide web and search engines, we have all types of information available to us almost instantaneously. Being able to search for answers to our questions and having access to all kinds of news from throughout the globe is indeed a blessing. The curses with this are the overload of information bombarding us every second of the day, and the accuracy of the information and news we receive. Human bias and interpretation are always at play. Even media outlets which used to be reliable sources of information insert opinion and slants to all of their reporting these days. But as we see in the verses from Matthew today, this danger is nothing new.
Jesus has another exchange with the Pharisees and Sadducees. They are clamoring for a sign which they hope to use against him. He refuses because he tells them they cannot even understand the signs which are now before them. Then leaving in a boat with his closest disciples, Jesus gives a warning to the disciples to be careful of the yeast of the Pharisees and Sadducees. The disciples misinterpret Jesus’s warning because they are focused on the bread which they forgot. After Jesus addresses their worry, he reiterates his warning. Now the disciples understand that the yeast which Jesus mentioned in his warning was actually the teachings and information. The ability of this information to change and inflate a person’s thinking can be a problematic influence.
There is a lot of information readily available in the world today. In the midst of all that information is truth and lies. The warning which Jesus gave the disciples is even more important for us today. We have witnessed how information can impact the way people think and act. When this information is designed to mislead or misinterpret, it can have a damaging result. Jesus’s warning reminds us to be cautious when receiving information. Know the source of the information. Crosscheck what you read or hear. Discuss the information with others, especially some who have a different point of view. If what you are receiving is in regard to faith and theology, make sure that it is in agreement with what you understand to be the nature of the Lord. Heed Jesus’s warning today and take the time to be cautious.
