Lyrics
Verse 1
I cannot tell why he, whom angels worship,
Should set his love upon the sons of men,
Or why, as shepherd, he should seek the wand’rers,
To bring them back, they know not how or when.
But this I know, that he was born of Mary,
When Bethl’hem’s manger was his only home,
And that he lived at Nazareth and laboured
And so the saviour, saviour of the world, is come.
Verse 2
I cannot tell how silently he suffered,
As with his peace he graced this place of tears,
Or how his heart upon the cross was broken,
The crown of pain to three and thirty years.
But this I know, he heals the broken-hearted,
And stays our sin, and calms our lurking fear,
And lifts the burden from the heavy laden,
For yet the saviour, saviour of the world, is here.
Verse 3
I cannot tell how he will win the nations,
How he will claim his earthly heritage,
How satisfy the needs and aspirations
Of east and west, of sinner and of sage.
But this I know, all flesh shall see his glory,
And he shall reap the harvest he has sown,
And some glad day his sun will shine in splendour
When he the saviour, saviour of the world, is known.
Verse 4
I cannot tell how all the lands shall worship,
When, at his bidding, every storm is stilled,
Or who can say how great the jubilation
When all the hearts of men with love are filled.
But this I know, the skies will thrill with rapture,
And myriad, myriad human voices sing,
And earth to heaven, and heaven to earth,
will answer,
“At last the saviour, saviour of the world, is King.”
Behind the Hymn
"I Cannot Tell" was written by William Young Fullerton (1857-1932), an Irish-born Baptist minister who served as president of the Baptist Union of Great Britain. The hymn has been given new life through a musical arrangement by Alanna Glover, who set the text to the traditional Irish tune "Londonderry Air" (popularly known as "Danny Boy"), creating a hauntingly beautiful pairing of theological depth and Celtic melody. Fullerton's text is structured around the repeated phrase "I cannot tell" — acknowledging the mystery and wonder of God's ways while affirming the certainty of His promises. Each verse explores a different aspect of Christ's work that transcends human understanding: why He came to earth, how He conquered sin and death, why He bears with sinful humanity, and when He will return in glory. The use of "Londonderry Air" — one of the most beloved melodies in the Irish and British folk tradition — gives the hymn an emotional depth that perfectly complements the text's sense of wonder and longing. It is a hymn that beautifully holds together mystery and certainty, acknowledging what we cannot fully explain while boldly declaring what we know to be true.
