No, I don't wonder anymore why some give in to Calvinism.
Calvinism gives a sinful source of security, and we all deeply want that.
I've been thinking about this response for a while, and there are so many reasons why it is just plain wrong, on so many levels.
1) It is outright uncharitable. It invents an "excuse" that is shallow and mocking, and presents Calvinism as shallow.
2) The poster has not demonstrated his claim that it is a "sinful" source of security.
3) It is incredibly uncharitable to assume that any Christian would reject truth for "security", since how can there be any security outside of truth? Yet this is how the poster wishes to represent Calvinists.
4) The main reason people "give in to Calvinism" is because we are thoroughly convinced, beyond ANY reasonable doubt, that it is what the Bible teaches. No more, no less. And as I have shared many times, Calvinism makes God a million times more holy, a million times more just, a million times more loving, a million times more merciful, a million times more gracious, and a million times more amazing!
5) Further, we don't need to "give in" to Calvinism to feel secure, since Southern Baptists are Arminian in their soteriology, and believe "once saved, always saved", and achieve security that way. Even though it doesn't jive with the rest of their soteriology, the SBC's recognize that eternal security (in one form or other) is Biblical. So there is no need to "give in" to Calvinism if "security was the main concern.
6) If the key to "security" in Christianity rests in Calvinism, does that mean that non-Calvinists are "insecure" in their confidence in being heaven-bound?
