People can think of Christianity as a system of punishments for breaking rules that are only opinions, but it can be clearly shown why breaking many of those rules is wrong and consequential even before considering punishment on a supernatural level.
Mocking someone with a group of friends clearly breaks the Golden Rule, and most people would agree it isn't only an opinion that a person shouldn't try to hurt people for fun.
Some people see Christianity as a belief in punishments for breaking rules that are only opinions. However, it can be reasoned why the teachings of Christianity are not only opinions and that the natural consequences are real even before a punishment is taken into account. Consider an example where someone is trying to get a laugh out of his friends by making fun of a girl who is doing nothing wrong.
Mocking someone with a group of friends clearly breaks the Golden Rule, and most people would agree it isn’t only an opinion that a person shouldn’t try to hurt people for fun. The girl made fun of could end up feeling the pain of what was said for years. The person looking for a laugh may not believe in any kind of religion and be clever enough to avoid any reprimands, but what else could happen as a result of acting this way?
For one, it may eventually become more clear to him what kind of damage he has done and then he’ll be left with the thoughts of how many people have been affected. In some cases the person being mocked could lash out too. The reader may be able to think of other natural consequences as well. The wisdom of Christianity helps people avoid many plainly seen problems and consequences even before consequences on the religious level are considered. Christians who help free the public from the misunderstandings concerning the ideas of rules and punishments in Christianity will encourage more people to consider becoming Christian.
