Waylan Owens is exactly right here:
You see, to say that “the Bible is not clear” with regard to some aspect of what life in Christ entails cannot be true, lest God be accused of demanding back from us something He refuses to reveal to us. What Moody must be arguing is that Christians of similar theological views on key doctrines disagree on some point of application of the Bible to life.
However, that does not mean that the Bible is not clear. It means that sinful Christian men and women do not come to a consensus on what the Bible teaches about a certain thing or behavior.
Saying that the Bible is not clear is a euphemism for, “we do not agree on what the Bible says.” And since that is the case, to ascribe to God, to His Word, and to His Holy Spirit lack of clarity when the real problem is our own disharmony and failure to hear Him clearly, is a very dangerous position to take.
The same kind of reasoning that Moody used is applied to music, which is why I address the issue in the same way as Dr. Owens in both of my books.
