I Cannot Tell

I cannot tell why He whom angels worship
Should set His love upon the sons of man
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
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 will reap the harvest He has sown
And some glad day His sun shall shine in splendour
When He the Saviour, Saviour of the world is known
