Englishman Samuel Trevor Francis (1834-1925) gave us this hymn. It’s one of the hymns I feel I’ve always known. The tune is Welsh.

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 ev’ry love the best:
’tis an ocean vast of blessing,
’tis a haven sweet of rest.
O the deep, deep love of Jesus!
‘Tis a heav’n of heav’ns to me;
and it lifts me up to glory,
for it lifts me up to thee.
