Thou wilt keep him in perfect peace, whose mind is stayed on thee; because he trusteth in thee.
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
Jesus guards such a mind like a garrison holds a city: perfect peace within while storms rage without. The word means literally to guard as with a garrison, so that turmoil cannot breach the inner citadel of trust.
AI summary
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.
