I think you've done that all your life, make false assumptions.
If you can’t state your principle, such that it can be objectively applied by others, then what else can I assume?
As it stands, you have basically said that there is a special way to interpret the Bible in order to get the real meaning, but you will not divulge the method so that others can apply it. So, essentially, if you were correct, you would be appointing yourself “Pope” of Biblical interpretation, since nobody else could reliably interpret anything, not having access to this secret principle of yours.
Now, obviously that is ridiculous and cannot be true. God did not reserve the truth of Scripture for you alone. So, I am left only with the possibility that your principle doesn’t really exist, or why else would you not divulge it?
