Daniel 4:28–33, King Nebuchadnezzar. For all of his great power and accomplishments, the king was on the verge of emotional and mental instability (or insanity). Hearing the voice and judgment from heaven evidently was the tipping point that drove him toward the side of insanity.
This illustrates the fact that for all of their greatness, many notable world leaders live their lives on the ragged edge between sanity and insanity, between mental and emotional stability and instability. Likely, these individuals are so compromised in their souls in that they have had to perform so many dastardly deeds to rise to the positions of power that they hold that they have become tormented deep inside. In reality, this can be the case with any human who has turned his back on his Creator.
Guilt, shame and a sullied conscience due to sin are irrepressible and cannot be expunged from a man’s heart. Such people can hardly live with themselves; they are trapped and can’t get out of their minds and bodies. Their deep inner guilt and shame perpetually keeps them at the brink of mental breakdown and madness.
Only the truth can set them free—the truth of redemption of sin through the preaching of the gospel message, through the love and forgiveness or Yeshua the Messiah and the supernatural transforming work of the Spirit of Elohim in one’s heart. For this reason, the servants of the Most High must keep preaching the gospel and holding sinners accountable for their sins against the Almighty.
