Why did these rulers hesitate? The text points to a deeper reason than just the threat of punishment: they valued human approval too much.
John Calvin and others emphasize that the underlying issue was a love for 'the glory of men' more than 'the glory of God.' These rulers were accustomed to honor, respect, and a prominent place in society. Openly following Jesus, who was rejected by the religious establishment, would cost them this.
A Trade-Off:
They were essentially weighing their desire for human reputation and status against the potential honor that comes from aligning with God. Their belief was real, but it was a 'weak' or 'lukewarm' faith (as some commentators suggest) because it wasn't strong enough to overcome their desire for worldly approval. This prevented them from making a bold, public confession.
