Evidence and reasoning from a former Christadelphian
Freedom had been hunted round the globe; reason was considered as rebellion; and the slavery of fear had made men afraid to think. But such is the irresistible nature of truth, that all it asks, and all it wants, is the liberty of appearing. ~ Thomas Paine, Rights of Man, 1791 ~
Even though most Christadelphians might say they believe because of prophecy, or because of current events, I don't think that is actually the case. Most Christadelphians believe quite simply because they happened to be born into Christadelphian families, were taught Christadelphian doctrines from a young age, and were raised in a largely Christadelphian culture. The evidence is clear. Had they not been born into such an environment, it is almost certain they would not be Christadelphians today.
