Throughout Scripture, God reveals Himself through dramatic contrasts: day and night, light and darkness, life and death, old man and new man. This is not merely a literary device, it is the very heartbeat of how God accomplishes His purposes in the earth.
When God moves, the evidence is undeniable. When Lazarus walked out of the tomb, no one could claim gradual improvement. When the blind received sight, no skeptic could attribute it to positive thinking.
