"Who at my need His life did spend"

Via Justin Taylor and Roy Ortlund:

My song is love unknown,
My Saviour’s love to me;  
Love to the loveless shown,
That they might lovely be.  
O who am I, that for my sake  
My Lord should take frail flesh and die?

 He came from His blest throne   
Salvation to bestow;   
But men made strange, and none 
The longed-for Christ would know:   
But O! my Friend, my Friend indeed,   
Who at my need His life did spend.   

Here might I stay and sing,   
No story so divine;   
Never was love, dear King!   
Never was grief like Thine.   
This is my Friend, in   
Whose sweet praise 
I all my days could gladly spend.  
Samuel Crossman, 1664
