If you've ever read the gospels of Matthew, Mark, Luke, and John you know that Jesus Christ had many confrontations with the unbelieving Jewish Pharisees, regardless of what the modern Christian Zionists say. And Jesus Christ didn't hate them, he wasn't an anti-semite. He was just telling them the truth and how they could change. He loved them. He didn't want them to go to hell, so he told them the truth, and some of them changed.
What bothers me is that a lot of modern Christians are just about exactly like the old Pharisees. The Pharisees did a lot of good things. They showed up at the synagogue every week. They tithed. They praised the Lord. Some of them even fasted two days a week. Most modern pastors would be happy to have this kind of Christian in his church, or even as deacons. But all this was external. Jesus Christ could see into the heart and see that these people were actually wicked, and they probably didn't even realize this.
And there's always been a kind of born again, even in the Old Testament. But you're born again by meditating on the word of God day and night, and doing what it says. See Psalm chapter one. So Jesus told them "Search the scriptures, for in them ye think ye have eternal life, and they are they that testify of me." Good advice for Christians today, too. If you have no faith at all right now start reading some of the King James version Bible every day, and before long you will have some faith.
Then the Pharisees weren't giving any alms to the poor, even though numerous places in the Old Testament tell you to do this. "Give alms of such things as ye have and behold all things are clean unto you," Jesus Christ told them. Luke 11:41. A lot of Christians today are giving nothing at all to the poor, and many churches are even telling them not to.
Then the Pharisees were proud and they seemed to want to be proud. Even though the Bible says in the Old Testament in numerous places that pride is a sin. "For, behold, the day cometh, that shall burn as an oven; and all the proud, yea, and all that do wickedly, shall be stubble." Malachi 4:1, for example. Jesus Christ told them that when they pray to smite themselves on the breast, look down, and say, "God, be merciful to me a sinner." Luke 18:10-14. Doing these things will help both Jews AND Christians get back on the right track.
