In the book of Job, God ultimately confronts Job with a lengthy discourse on His sovereignty as the Creator of the universe. Because of His power, He reminds Job that He owes no one an explanation for whatever decrees He makes.
It's right and proper to be humbled, as Job was, by God's power. But those who belong to the Lord may also draw comfort from His power, being assured that He tenderly couples His power with a commitment to lovingly care for us. This majestic hymn by Isaac Watts leads me to worship the Lord for both His magnificent power and His trustworthy love.
