Terms such as "trinity" or "three persons of God" do not come from the Bible but they are useful by simplifying words to express what the Bible says about God. The statement of the Bible on this subject reveals itself not as easy as one might think. In the Bible we find no standing to be discussions about the nature of God. Rather, you can only from hints form an image, which is only evident in the sum. However, human considerations and religions enjoy keeping with the abstract discussion of such things - typical that the Bible is very different here. The difficulties to grasp the nature of God, based so far just on the Bible that something only implies that man also can be hard to understand - but this is why is not any less true: Our intellect and his understanding of opportunities are not namely the yardstick where the reality of God would be oriented.

The Holy Spirit is not the father. But all three are the same G. To explain it with a simple image: the molecule H2O (water) occurs us in three completely different manifestations against: namely as ice, liquid water and water vapor. All three are the same element - and yet they are not identical to each other: ice and steam are not identical, even though both are H2O.

This is difficult to understand for us and therefore more likely starting point for strange doctrines. Secularized nominal Christians often have nebulous ideas about the relationship of Jesus to the F
