Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee.
The heart of this promise rests on God's unchangeable decree, not merely on our wavering emotions. When Isaiah speaks of the steadfast mind kept in peace, he means that all who hope in Him shall enjoy eternal peace because His purpose itself is fixed and eternal, not because our feelings remain constant.

The Church is a strong city with salvation itself as its walls. God has appointed this defense; those destined for salvation find in it their true protection, far stronger than any rampart of stone. The righteous who keep the truth are the city's real inhabitants and strength.

Commenting on Isaiah 26:1-4
Peace repeated twice in the Hebrew, peace, peace, declares its certainty, its constancy, and its abundance. This is the true peace of God through Christ, not imaginary comfort; it flows from a mind fixed on His covenant, His faithfulness, and His power to perform what He has promised.
