Long ago Isaiah saw a day coming when the Lord’s people would sing a new song of confidence and salvation. In a strong city, with gates open to welcome the righteous, the prophet foresaw the faithful singing:
The steadfast of mind
You will keep in perfect peace,
Because he trusts in You. (Isa. 26:3)
Only when our mind stays on God can we have such perfect peace. Keeping our minds on Him is both a blessing to us in itself and the way to be further blessed.
Minds set anywhere other than on God cannot remain steadfast because all else but Him is mutable, shifting and changing. But in Him, the faithful can build their house upon the rock (Matt. 7:24-27), and be in a kingdom that cannot be shaken (Heb. 12:26-28).
Trusting in the Lord is the soundest thing we can possibly do. So Isaiah further saw them singing:
Trust in the LORD forever,
For in GOD the LORD,
we have an everlasting Rock. (Isa. 26:4)
Let us confidently sing the same songs of faith and praise today and fulfill anew the vision of the prophet.
