Gullibility - a key to heaven?

[kılıç_mehmet]

Although it can be argued that not all believers in Christianity and Islam are gullible, it can be argued that it's all that is required to accept Christianity and Islam or that it can be the primary factor (along with bias).

What I mean by that, is that since believers are promised paradise, many believers can be gullible people. It cannot be argued that every single believer has not believed out of gullibility.

But then if gullibility can lead to belief, then why is belief always praised?

Well, most of the time you don't "accept" any of the religions you've mentioned. You're simply born into it. If there are any converts that you know, maybe you should check them for the gullibility factor.
