There are some eternal truths that would be true, whether said decades ago, or now. And whether VPW said them, or someone else did.
He himself was the one who said that "every generation needs to make the Word its own," ie, learns to apply Biblical principles in their generation and circumstances. Hmmm. Did he mean that (for example) "kindness" changes?
However, I don't trust what he said or wrote. Wasn't too sure about some things when first heard in PFAL; definitely am not sure now. Everything he said or wrote needs confirmation from some other source(s), sources that are in no way Way related.
