Priceless is thy treasure,
Book of grace divine,
Here, in love’s own measure,
God’s heart speaks to mine.
Joy my soul is swelling,
As these lines I scan;
God’s own message telling
Of His love for man.

No well-known hymn by this exact title or opening lines appears in standard references (e.g., Hymns Ancient & Modern, Gospel Hymns, or major denominational collections). The style suggests a late-19th or early-20th-century devotional text, possibly from a British or American Sunday-school hymnal, but no specific author is clearly associated. Could be a translation or a lesser-known piece by a writer such as Frances Ridley Havergal or similar, but without corroborating evidence it must be treated as anonymous.
