The problem with many theologies is not that they are egregiously heretical and non-biblical, but rather that they seem plausible, and thusly find wide acceptance and circulation. For many theologies appeal to a less than sufficient knowledge and application of Scripture. Because then the average Christian is ignorant of the teachings of the Bible, a theology may find wide acceptance due to its plausibility, not its level of biblical adherence.

Furthermore, because a theology seems plausible does not make it true. Where our ignorance of Scripture takes over, we are not free to improvise with plausible solutions. Rather we should search the Scriptures to see what they teach and let this teaching be our theology.

What’s plausible isn’t always true, nor automatically true. “What you say seems possible, but let’s see what the Scriptures have to say on this issue, not conjecture amongst ourselves.” The mind can fabricate loads of varied solutions to a problem, but if one solution is already clearly written out in a book and we claim to adhere to that book, then varied solutions should not be our goal, but the solution presented in the book. I am not interested in what you may think the solution to such and such a problem is but I am wholly interested in God’s answer to said “problem.”

The problem with many theologies is that they seem plausible and since we are ignorant of the Scriptures, we readily accept them because they seem possible. Our God is the God of the impossible. I should fear if I am able to dream up a solution, for Christianity is wholly committed to looking to external revelation for answers not introspection. Introspection leads to plausible answers, but not necessarily true answers.

Arminianism is plausible but untrue, and it will seem more plausible with the less Scripture you know.
