“Be strong and courageous. Do not be afraid or discouraged because of the king of Assyria and the vast army with him, for there is a greater power with us than with him. With him is only the arm of flesh, but with us is the Lord our God to help us and to fight our battles.” And the people gained confidence from what Hezekiah the king of Judah said.
2 Chronicles 32:7-8 NIV
When Sennacherib, king of Assyria, marched his army toward Judah, Hezekiah did not simply pray. Instead, he prepared. He consulted his military officials and blocked off the city’s water springs. He then repaired the broken sections of the wall and built towers on it. Additionally, he reinforced the terraces of the City of David and produced large numbers of weapons and shields (2 Chronicles 32:3–5). It was thorough, practical, and wise. Yet it was not enough on its own, and Hezekiah knew it. Building a wall of faith and prayer would prove to be the real work. No enemy could ever tear that down.
Physical Walls Cannot Bear the Full Weight
Physical preparations have their place. However, they carry an inherent limit. Human beings build physical walls, and human beings can tear them down. Men forge weapons, and men can seize those same weapons in battle. Therefore, placing full trust in any physical defence is a misplaced confidence. Hezekiah recognised this early, and he did not wait for Sennacherib to breach the walls before responding.
So he turned to his people with words that no stone barrier could match. He told them not to fear the king of Assyria and his vast army. A greater power stood with them. Sennacherib had only the arm of flesh, Hezekiah reminded them. But with God’s people was the LORD himself, present to help them and fight their battles (2 Chronicles 32:7–8). The people gained confidence from these words.
This was building a wall of faith and prayer. Indeed, it proved to be the most important structure Hezekiah ever raised. Physical walls rise from human effort and fall to human force. But a wall of faith rises from the character and testimony of God Himself. Therefore, no enemy can bring it down.
The Wall That Cannot Fall
Sennacherib did not back down quietly. He ridiculed the God of Israel and taunted the people, trying to shake their confidence. Yet Hezekiah’s faith did not waver. Rather than retreating into panic, he held his ground. He kept his trust anchored in who God is, not in what the circumstances looked like.
The story, however, does not end with faith alone. Hezekiah raised a second wall: prayer. Together with the prophet Isaiah, he cried out to heaven about the crisis (2 Chronicles 32:20). It was not a transactional prayer — not a prayer held alongside a backup plan. It was a prayer of absolute reliance. The kind that sets every alternative aside and calls on God as the only sure hope.
God answered. He then sent an angel who annihilated all the fighting men, commanders, and officers in the Assyrian camp. Sennacherib withdrew to his own land in disgrace. His own sons killed him in the temple of his god (2 Chronicles 32:21). Indeed, the LORD saved Hezekiah and the people of Jerusalem and took care of them on every side (2 Chronicles 32:22).
Building a Wall of Faith and Prayer That Holds
The pressures you face today may not look like an Assyrian army, but the principle remains the same. Physical resources and human strategies have their place. Yet ultimately, they carry a ceiling — they can fail, run out, or collapse entirely.
Building a wall of faith and prayer is different. It draws from a source that never runs dry and a defence that no external force can break. Such faith does not rest on personal resolve but on the knowledge of who God is. He is the one who fights for those who trust him. Such prayer is not a last resort. Rather, it is the first response of someone who has already decided that God alone is enough.
In Christ Jesus, through the help of the Holy Spirit, that kind of wall is available to every believer. Moreover, when you raise it in Him, overwhelming victory comes with it.
Living It Out
Bring your pressures before God, not as a last resort but as your first response. Build a wall of faith grounded in who He is. Then build a wall of prayer that surrenders every alternative to Him alone. He fights for those who rely on Him completely.
