John 13: Peter... said unto Him, Lord., dost Thou, &c

Incomprehensible to man
The strange humility Divine
Till Jesus doth Himself explain
His own mysterious love's design:
Wondering we ask how can it be,
That God should wait on man below.
That the Most-High should stoop to me.
And wash the sinner white as snow!

When Jesus at his feet he saw,
Peter might well repeat the word
"From a vile sinful man withdraw.
Holy and just and heavenly Lord!"
But therefore will the Saviour stay
For this in human likeness born.
To purge our guilty stains away,
And to a saint a sinner turn.
