Ok, I'll give you the verse from Hebrews, but my point still stands in that you are believing something without *any* evidence.

You base it entirely on the bible, but you have no evidence that the events of the bible ever happened.

Eg, you used the examples of Abraham and Moses, except that the evidence shows that those people never existed. I can give you more information or references for this if you like, but the short version is that the events of Genesis to Deuteronomy never actually happened. There was no slavery in Egypt, no liberation by Moses, the nation of Israel formed from a disparate lot of Canaanite tribes that banded together, and were even polytheistic at the start. The god of the bible was only one of a pantheon. (two actually, since in Hebrew, two different names are used for god, and they are the names of two separate gods; El and Yahweh)

So, you can't use the example of god being faithful to ancestors if they never existed in the first place.

Also, the author giving examples of those ancestors isn't really evidence. It's anecdotal, hardly objective at all. And "logical reasoning"? Hardly, there are plenty of logical fallacies and contradictions all throughout the bible.
