Carson, On the Bible is Not a Supermarket

From How Long, O Lord? Reflections on Suffering and Evil:

However hard some things are to understand, it is never helpful to start picking and choosing biblical truths we find congenial, as if the Bible is an open-shelved supermarket where we are at perfect liberty to choose only the chocolate bars. For the Christian, it is God's Word, and it is not negotiable. What answers we find may not be exhaustive, but they give us the God who is there, and who gives us some measure of comfort and assurance. The alternative is a god we manufacture, and who provides no comfort at all. Whatever comfort we feel is self-delusion, and it will be stripped away at the end when we give an account to the God who has spoken to us, not only in Scripture, but supremely in his Son Jesus Christ.
