I just think it is when people get too fanatic about their religious beliefs and start to link them to the problems that you have a serious issue. We did have an example of it on the forum a month or so ago. A person who thought they had done wrong in the ways of the religion and their God and ended up as they were. They wanted to know how they right the wrongs in a religious way so as not to be punished any more. To have that kind of thinking must be wrong and bad for you? You must do everything by the book. Or else you feel / imagine that you will pay in life. Far from a healthy way of thinking of all. And if preachers do preach such rubbish then they are wrong to do so. It is like scaring people into believing. That is not a choice. That is a forced belief. And that is the only thing I have trouble with. Other than that it is each to their own.

That is bad, but not what the bible teaches. The New Testament teaches grace, which is the opposite of legalism. Legalism is what you just explained: trying to complete a list of commands to please an angry God. Grace is what God wants us to live by in the New Testament. Which is living free, without worrying about commands at all. The New Testament says that if you simply live by love, you've covered all the commands. And that love covers a multitude of sins.
Galatians 5:1 says, "It is for freedom that Christ has set us free. Stand firm then and do not let yourselves be burndened again by a yoke of slavery." Jesus came to break the yoke of legalism. In the same book, Chapter 3, he talks about legalism. He says in verse one, "You foolish Galatians! Who has bewitched you? Before your very eyes Jesus Christ was clearly portrayed as crucified. I would like to learn just one thing from you: Did you receive the Spirit by observing the law, or by believing what you heard?" That is, of course, a rhetorical question meaning that they received the Spirit by believing and not by observing the law. He continues, "Are you so foolish? After beginning with the Spirit, are you now trying to attain your goal by human effort? Have you suffered so much for nothing--if it really was for nothing? Does God give you his Spirit and work miracles among you because you observe the law, or because you believe what you heard?"
He is saying that since you received the Spirit by believing and not by human effort, don't try to receive a miracle from God by human effort. Christianity is a life of grace, which means: God giving us what we do not deserve, as opposed to mercy, which means: God not giving us what we do deserve. We are to simply believe for the miracle, just as much as believing for God's Spirit and salvation, without striving to do this or that command. Jesus broke the yoke of legalism of the old testament. We are now in the day of Grace. The OT was the Day of Legalism. It is for freedom that Christ came. He came to set us free.
