I learned the tune before I learned this hymn. The first time I sang it was with my cousin Erik on Christmas night of 1996. Erik had a really turbulent life and that Christmas was the first time I had seen him in 4 years. In that span of time, he got religion and he and I were sitting in the living room singing while he played guitar. He died in June of 2011 and it’s one of my happy memories of him.

O the deep, deep love of Jesus, vast, unmeasured, boundless, free!
Rolling as a mighty ocean in its fullness over me!
Underneath me, all around me, is the current of Thy love
Leading onward, leading homeward to Thy glorious rest above!

O the deep, deep love of Jesus, spread His praise from shore to shore!
How He loveth, ever loveth, changeth never, nevermore!
How He watches o??er His loved ones, died to call them all His own;
How for them He intercedeth, watcheth o??er them from the throne!

O the deep, deep love of Jesus, love of every love the best!
??Tis an ocean full of blessing, ??tis a haven giving rest!
O the deep, deep love of Jesus, ??tis a heaven of heavens to me;
And it lifts me up to glory, for it lifts me up to Thee!
(HT: Net Hymnal)

The group Selah did a recording of the song (which is the most popular result if you do a search on YouTube) but I prefer congregational singing. In this particular video, it’s the Moody Men’s Choir singing as part of a worship service and I love the deep voices of the men which are slightly audible over the congregation’s singing.
