"As a bridegroom rejoices over his bride—so will your God rejoice over you!" Isaiah 62:5
How heart-cheering to the believer, is the fact that God delights in His redeemed people!
We cannot see any reason in ourselves, as to why the Lord should take pleasure in us. We cannot take delight in ourselves, for we often have to groan being burdened, conscious of our sinfulness and deploring our unfaithfulness. We also fear that God's people cannot take much delight in us, for they must perceive so much of our imperfections and our follies—that they may rather lament our infirmities, than admire our graces.
But we love to dwell upon this transcendent truth, this glorious mystery: that as the bridegroom rejoices over the bride—so does our God rejoice over us! In what strong language He expresses His delight in His people! Who could have conceived of the Eternal One as bursting forth into a song? Yet it is written, "He will take great delight in you—He will rejoice over you with singing!" Zephaniah 3:17
As He looked upon His newly created world, He said, "It is very good"—but He did not sing.
As He views His works of providence—I do not read that He sings.
But But when He gazes on His redeemed people—the purchase of Jesus' blood, His own chosen ones—it seemed as if the great heart of the Infinite could restrain itself no longer—but, wonder of wonders and miracle of miracles—God, the Eternal One, sings out of the joy of His soul!
"He will take great delight in you, He will quiet you with His love, He will rejoice over you with singing!"
