Take heed and beware of the leaven of the Pharisees
Matthew 16:5 And when his disciples were come to the other side, they had forgotten to take bread. 6 Then Jesus said unto them, Take heed and beware of the leaven of the Pharisees and of the Sadducees. 7 And they reasoned among themselves, saying, It is because we have taken no bread. 8 Which when Jesus perceived, he said unto them, O ye of little faith, why reason ye among yourselves, because ye have brought no bread? 9 Do ye not yet understand, neither remember the five loaves of the five thousand, and how many baskets ye took up? 10 Neither the seven loaves of the four thousand, and how many baskets ye took up? 11 How is it that ye do not understand that I spake it not to you concerning bread, that ye should beware of the leaven of the Pharisees and of the Sadducees? 12 Then understood they how that he bade them not beware of the leaven of bread, but of the doctrine of the Pharisees and of the Sadducees.
First of all, leaven does not mean sin, it means the doctrines of the society you live in. The doctrines of the Pharisees were leaven, but so are the doctrines of Islam and the doctrines of Catholocism and the doctrines of Hindus, etc. Telling you that you must wash your hands before eating is a doctrine of man and is leaven. These doctrines are not necessarily sin unless they are in rebellion to the word of God. So yes, the leaven is associated with sin because the doctrines of Jezebel are in rebellion to God, but technically they refer to teachings which have the potential to short circuit the word of God. So then, to take heed and beware of the leaven means you need to examine the doctrines that you are embracing, are they based on the word of God? That is to take heed. If not, beware of them, they are like a snake hidden in the grass.
Let us consider three examples of the leaven around the rapture.
1. No one will know who the Antichrist is until after the rapture. This is based on Paul saying that after the restrainer steps aside the man of lawlessness (the Antichrist) will be revealed. They interpret the restrainer stepping aside as the rapture (I agree) and they interpret the man of lawlessness to be the Antichrist (I agree). But who is he revealed to? According to Paul he is revealed to those left behind and the unbelievers. Who was the restrainer restraining? It was the man of sin, the Antichrist kingdom. If those who are raptured are restraining the Antichrist, how are they doing that if they can't see him? Paul is not saying that those who are raptured cannot see the Antichrist, only that those who are left behind, those who are asleep, they will wake up after the rapture and then see him when it is too late. This doctrine encourages people to have the attitude "no one knows so don't bother looking". It is a drug to put you to sleep.
2. No one knows the day or the hour, this is the most famous doctrine, but it is also leaven. Jesus said no one knows the day or the hour, so then how can this be leaven? Well they again use this to say "no one knows, so stop talking about it" and again it is a drug to put you to sleep. Go find where Jesus said "no one knows the day or the hour" and He follows that up with "therefore you have to watch". The farmer doesn't know the day or the hour he will harvest when he plants his seeds, therefore he has to watch. The pregnant woman doesn't know the day or the hour she will have the baby therefore you have to watch. You don't know the day or the hour that a thief will come, therefore you hire a night watchman.
3. The Jews will rebuild the temple. First of all there are two Greek words that we translate as "temple" in English. One means the building, like a Cathedral or Mosque. The other word refers to the Holy sanctuary, the Holy Place and the Holy of Holies. All of the verses that would indicate there is a temple during the tribulation refer to the Holy Sanctuary. Even though the New Testament refers to the Temple complex, the building, over sixty times, never once does it indicate that building will be present during the tribulation. Also there is no prophecy in the Old Testament of the Jews rebuilding a third temple. Instead there is a prophecy that in the last days the tabernacle of David will be raised. The Holy Sanctuary can be present in both the Tabernacle and Temple. Now because of this doctrine of the temple being rebuilt many Christians are focused on this sign saying that when the Jews begin to rebuild the temple, or when they get a peace plan that allows them to rebuild the temple, that is the sign of the Lord's coming. So instead of watching for all the signs everyone focuses on this one sign. What is the harm in that? Well in June of 2025 Israel had a ceremony where they burned one of their certified red heifers to ashes and the temple institute collected those ashes for purifying the temple (meaning the Holy Sanctuary). They said the ceremony was done according to the law of Moses. That means they have restarted the priesthood and the oblations and they also must have raised the tabernacle of David. You cannot perform this ceremony unless the tabernacle of David has been raised because you must be looking into the temple (the Holy Sanctuary) at the time of this ceremony. That is the prophecy, according to the Old Testament the Tabernacle of David will be raised again in Shiloh and that is precisely what took place in June of 2025. So all the Christians worldwide were alerted, right? Nope, they are all looking at the Temple mount and didn't pay any attention. Leaven makes it easier to eat bread. The word of God is bread. To watch for the Lord's return is hard, but if all I have to do is watch the temple mount, well that is easier.
Hence the Lord's word, take heed and beware the leaven of the Pharisees.
