Isaiah 26:1-4 (NLT)

1 In that day, everyone in the land of Judah will sing this song:

Our city is strong!
    We are surrounded by the walls of God’s salvation.
Open the gates to all who are righteous;
    allow the faithful to enter.
You will keep in perfect peace
    all who trust in you,
    all whose thoughts are fixed on you!
Trust in the Lord always,
    for the Lord God is the eternal Rock.
