What does Isaiah 26:3 mean?
What is the meaning of Isaiah 26:3?

You will keep

• The verse begins with a promise, highlighting God Himself as the active guardian.

• “He will not allow your foot to slip; He who watches over you will not slumber” (Psalm 121:3) shows the same vigilant care.

• Jesus said, “No one can snatch them out of My Father’s hand” (John 10:29), reinforcing divine security.

• Jude points to God’s preserving power: “Now to Him who is able to keep you from stumbling” (Jude 24).


in perfect peace

• Scripture speaks of peace that is complete, undisturbed, and supplied only by God.

– “Peace I leave with you; My peace I give to you” (John 14:27).

– “The peace of God, which surpasses all understanding, will guard your hearts and your minds” (Philippians 4:7).

• God’s blessing echoes the same fullness: “The LORD lift up His countenance toward you and give you peace” (Numbers 6:26).

• Christ Himself “is our peace” (Ephesians 2:14), making this promise possible for every believer.


the steadfast of mind

• A steadfast mind is fixed, settled, and undivided.

– “He will not fear bad news; his heart is steadfast, trusting in the LORD” (Psalm 112:7).

– “Set your minds on things above, not on earthly things” (Colossians 3:2).

• Scripture warns against the opposite: “He who doubts is like a wave of the sea, blown and tossed by the wind” (James 1:6).

• Steadfastness focuses thought, affection, and will on God rather than circumstances.


because he trusts in You

• Trust is the ground on which peace and steadfastness stand.

– “Trust in the LORD with all your heart… and He will make your paths straight” (Proverbs 3:5-6).

– “Blessed is the man who trusts in the LORD, whose confidence is in Him” (Jeremiah 17:7).

• Trust looks upward, not inward, for security. Hebrews 11:6 reminds us, “Without faith it is impossible to please God.”

• When we commit all to Him—“Commit your way to the LORD; trust in Him, and He will do it” (Psalm 37:5)—He responds with sustaining peace.


summary

Isaiah 26:3 assures believers that God Himself actively guards the one whose thoughts are anchored in Him. Perfect peace is not a fragile calm but God’s own unshakable serenity, granted to minds that remain fixed on His character and promises. The key is wholehearted trust: as we rely on the Lord rather than ourselves, He continually surrounds us with peace that the world cannot give and cannot take away.
