A Song of Salvation

Isaiah 26:1-4 (NKJV)
1 In that day this song will be sung in the land of Judah:
“We have a strong city;
God will appoint salvation for walls and bulwarks.
2 Open the gates,
That the righteous nation which keeps the truth may enter in.
3 You will keep him in perfect peace,
Whose mind is stayed on You,
Because he trusts in You.
4 Trust in the Lord forever,
For in YAH, the Lord, is everlasting strength.”
