You will keep him in perfect peace, whose mind is stayed on You, because he trusts in You.
Listen to the "Verse by Verse" episode covering this scripture.
God offers real peace of mind to those who focus on Him and trust in Him. As the Faith Chapter shows, “Now faith is the substance of things hoped for, the evidence of things not seen” (Hebrews 11:1).
Remembering that God has all power and keeping Him always in mind is an effective antidote to the worry and fear that destroy peace of mind.
