Isaiah 26:15
Thou hast increased the nation, O LORD, thou hast increased the nation: thou art glorified: thou hadst removed it far unto all the ends of the earth. Thou hast increased the nation, O LORD, thou hast increased the nation: thou art glorified: thou hadst removed it far unto all the ends of the earth.
The enlarging of the nation is bound up with the taking away of sins. That removal is the work of God’s grace, bestowed freely and not earned. By that gracious act the sinner is given access to the riches of His glory.
