The Burning Bush: God’s Holy Ground and the Call of Moses. A shepherd in the wilderness, an unquenchable flame, and a voice from heaven—Exodus 3 presents one of the most defining moments in salvation history. The burning bush is more than a dramatic call; it reveals God’s holiness, His covenant name, and His plan to redeem His people. For every believer, it’s a reminder that God still calls ordinary people to extraordinary obedience.
