There is one example of Jesus using guilt and fear -- scare tactics -- on His listeners. It's an audience He summoned. The scribes. Summoned like demons! The pen-men of the day. Rewriting scripture their own way. And getting it very wrong.
Check out Mark 3:22-30
Jesus tells them they must stop labeling God's work as belonging to the Devil. That kind of blasphemy will glug up your heart so hard-and-fast you'll be completely deaf to the ever gentle voice of the Holy Spirit. The unpardonable -- because you're unreachable -- sin.
Jesus loved even the religious leaders who hunted and harassed Him. He didn't want them to miss or misname God's voice. He wanted them to be drawn to Him the way Nicodemus was. Seeking. Teachable. Even if it was at night.
Jesus meets people where they are. And if they're hell-bent on leading themselves or others off a spiritual cliff… He will pull out all the stops to save them.
