The Sundial of Ahaz
The sundial of Ahaz is used as a sign from God to confirm His promise to extend Hezekiah's life. The shadow moving backward symbolizes God's control over time and nature.
This symbol highlights God's sovereignty over creation and His ability to intervene miraculously in the natural order. It also underscores His faithfulness in fulfilling His promises.
Sundials were ancient timekeeping devices, and the movement of the shadow was a natural phenomenon that people relied on to tell time. The reversal of the shadow would have been a clear and undeniable sign of divine intervention.
