Recently I have started to wonder about this particular issue. Is blasphemy an old term we should no longer use, or does it still apply? My problem is the rampant manner in which believers declare every random idea that pops into their head as being "from God". For instance, a pastor gets up and declares that last night God lead him to a certain sermon. However it turns out that another pastor will give an opposite sermon, yet claim the same authority, God Himself. Should I demand a sign? That's how it was done in the old testament. Presenting your opinion is one thing, but saying its from God, I would think, is quite another. Am I blowing things out of proportion, or is this taking God's name so lightly, something that needs to be addressed?
