why is there so much religious division?..if we all use the same bible, shouldn't we all come to the same?

Question

conclusions?

Anthea H, to what religious organization do you belong?

Answer 1

That is because we approach God with different Motives..
Some approach God because they are distressed or in Problem, Some approach for wealth or power, Some approach because they are Inquisitive and some approach because they simply know that God is Great.
Though the scriptures tells the same truth, people do not accept it at it is, but as they like....Hence there is so many divisions...

Answer 2

Many factors have contributed to the development of new religious groups. Some have said that the various religions all represent different ways of presenting religious truth. But a comparison of their teachings and practices with the Bible indicates, rather, that the diversity of religions is because people have become followers of men instead of listening to God.

Who is the instigator of such religious confusion? The Bible identifies Satan the Devil as “the god of this system of things.” (2 Cor. 4:4) It warns us that “the things which the nations sacrifice they sacrifice to demons, and not to God.” (1 Cor. 10:20) How vitally important, then, to make sure that we really are worshiping the true God, the Creator of heaven and earth, and that our worship is pleasing to him!

Rom. 10:2, 3: “I bear them witness that they have a zeal for God; but not according to accurate knowledge; for, because of not knowing the righteousness of God but seeking to establish their own, they did not subject themselves to the righteousness of God.” (People may have God’s written Word but lack accurate knowledge of what it contains, because they have not been taught properly. They may feel that they are zealous for God, but they may not be doing what he requires. Their worship is not going to please God, is it?)

The Bible does not agree with the modern view that there are many acceptable ways to worship God. Ephesians 4:5 says there is “one Lord, one faith.” Jesus stated: “Narrow is the gate and cramped the road leading off into life, and few are the ones finding it. . . . Not everyone saying to me, ‘Lord, Lord,’ will enter into the kingdom of the heavens, but the one doing the will of my Father who is in the heavens will.”—Matt. 7:13, 14, 21; see also 1 Corinthians 1:10.

The TRUE religion will stick to the Bible, will not add to or take away any of it's teachings. It will work in harmony with the Lords Prayer to Hallow (hold sacred) Gods Name.
Here's one truth to check in your Bible - Psalms 83:18
