“There is value in ranking our level of certainty about what Scripture teaches. Practically speaking, a scale of four categories is helpful. First are those things about which there is no doubt: the most basic fundamentals of the faith. These are matters of absolute conviction. Second are those matters where we are aware there are differences of opinion, but about which one is pretty certain of the preferred view. We would describe one’s view here as a firm conviction. A third category is another case where there is a difference of opinion, but this time the feeling is that when God brings us to heaven, we may find out the other person was right. This category we would call a soft conviction. Last are those areas where we might as well flip a coin, because none of us really knows. This would be genuine uncertainty.”
