We all (reportedly) worship the same God, are saved by the same Savior, and seek the wisdom of the same Holy Spirit.
So why do we come out of that with COMPLETELY different and opposing interpretations of the same scriptures?
The Bible is plain in what it states, and the Bible says that some have a form of godliness, but deny the power thereof, ever learning but never able to come to the knowledge of the truth, but this has to do with their sin problem that they do not realize that the Lord knows them that are His having this seal, that everyone that names the name of Christ depart from iniquity, and awake to righteousness, and sin not, but some do not have the knowledge of God, but they hold unto sin and think they are alright.
But a person does not need the Spirit to know David was king in Israel, and thou shalt not steal, and information like that for it is plainly stated.
So why the different interpretations.
That is because some people have a different belief concerning reality, and it becomes their foundation for the interpretation of scriptures.
If people want to enjoy sin they justify it, which many people do that by saying they cannot abstain from sins, although the Bible says if a person hates sin, and does not want sin, by the Spirit they can abstain from sins, and God will not allow them to be tempted as hard as the world, and will give them an escape from the temptation.
It is obvious when the Roman Empire embraced Christianity that they did not get rid of their pagan ways, and it became their foundation for the interpretation of scriptures.
Joseph Smith has a different view of reality, and many other like the new age movement that interpret the Bible according to the occult, and evolution, because that is what their reality is about, and others from that type of thinking like Christian Science, and Scientology, that seem to attribute God to the natural.
But a lot of people go by their denomination, and it is their foundation, and if it is false they do not see it the right way.
But the Bible is plain if people take it as it is without a belief that is not part of the Bible, or wanting to enjoy sin and justify it.
